Apache Ant

May 7th, - Apache Ant Released

Apache Ant is now available for download as source or binary (with and without dependencies) from cromwellpsi.com

Key features of the release are

• new task augment allows to add attributes or nested elements to previously defined references
• numerous bug fixes and improvements as documented in Bugzilla and in WHATSNEW

Apache Ant

Februrary 8th, - Apache Ant Released

Key features of the release are

• Lexically scoped local properties, i.e. properties that are only defined inside a target, sequential block or similar environment. This is very useful inside of <macrodef>s where a macro can now define a temporary property that will disappear once the task has finished.
• <import> can now import from any file- or URL-providing resource - this includes <javaresource>. This means <import> can read build file snippets from JARs or fixed server URLs. There are several other improvements in the area of import.
• Various improvements to the directory scanning code that help with symbolic link cycles (as can be found on MacOS X Java installations for example) and improve scanning performance. For big directory trees the improvement is dramatic.
• The way developers can extend Ant's property expansion algorithm has been rewritten (breaking the older API) to be easier to use and be more powerful. The whole local properties mechanism is implemented using that API and could be implemented in a separate library without changes in Ant's core. Things like the yet-to-be-released props Antlib can now provide often required "scripty" fuctions without touching Ant itself. At the same time the if and unless attributes have been rewritten to do the expected thing if applied to a property expansion (i.e. if="${foo}" will mean "yes, do it" if ${foo} expands to true, in Ant it would mean "no" unless a property named "true" existed). This adds "testing conditions" as a new use-case to property expansion.
• A new top-level element <extension-point> assists in writing re-usable build files that are meant to be imported. <extension-point> has a name and a dependency-list like <target> and can be used like a <target> from the command line or a dependency-list but the importing build file can add targets to the <extension-point>'s depends list.
• Ant now requires Java or later
• new task include provides an alternative to <import> that should be preferred when you don't want to override any targets
• numerous bug fixes and improvements as documented in Bugzilla and in WHATSNEW

Apache Ivy

October 8, - Apache Ivy Released

Apache Antidote Retired

April 4th, - The Apache Ant Project Retires Apache Antidote, the Ant GUI

The Antidote subproject was once started to provide a GUI for Ant at a time where IDE support for Ant was far from usable. Unfortunately it never attracted a developer community of its own.

At the same time IDE support for Ant has become ubiquitous by now and there is little reason to have a GUI just for Ant. This makes it even less likely that volunteers will start to spend time working on it.

Antidote's development has been stalled for years now, despite some efforts to rejuvenate it by single developers. Therefore the Ant developers have chosen to retire Antidote.

Antidote will no longer be developed by the Ant project; its CVS module will be shut down.

If you are interested in Antidote's sources to learn from or build on it, you can find snapshots at cromwellpsi.com

Sun has released an introductory article on Apache Ant on their Dot-Com Builder site on May 30 See cromwellpsi.com

Introduction

Java and the JVM (Java’s virtual machine) are required for many kinds of software, including Tomcat, Jetty, Glassfish, Cassandra and Jenkins.

In this guide, you will install various versions of the Java Runtime Environment (JRE) and the Java Developer Kit (JDK) using . You’ll install OpenJDK as well as the official JDK from Oracle. You’ll then select the version you wish to use for your projects. When you’re finished, you’ll be able to use the JDK to develop software or use the Java Runtime to run software.

Prerequisites

To follow this tutorial, you will need:

Installing the Default JRE/JDK

The easiest option for installing Java is to use the version packaged with Ubuntu. By default, Ubuntu includes Open JDK 11, which is an open-source variant of the JRE and JDK.

To install this version, first update the package index:

Next, check if Java is already installed:

If Java is not currently installed, you’ll see the following output:

Execute the following command to install the default Java Runtime Environment (JRE), which will install the JRE from OpenJDK

The JRE will allow you to run almost all Java software.

Verify the installation with:

You’ll see the following output:

You may need the Java Development Kit (JDK) in addition to the JRE in order to compile and run some specific Java-based software. To install the JDK, execute the following command, which will also install the JRE:

Verify that the JDK is installed by checking the version of , the Java compiler:

You’ll see the following output:

Next, let’s look at how to install Oracle’s official JDK and JRE.

Installing Oracle JDK 11

Oracle’s licensing agreement for Java doesn’t allow automatic installation through package managers. To install the Oracle JDK, which is the official version distributed by Oracle, you must create an Oracle account and manually download the JDK to add a new package repository for the version you’d like to use. Then you can use to install it with help from a third party installation script.

The version of Oracle’s JDK you’ll need to download must match version of the installer script. To find out which version you need, visit the page.

Locate the package for Focal, as shown in the following figure:

In this image, the version of the script is . In this case, you’ll need Oracle JDK You don’t need to download anything from this page; you’ll download the installation script through shortly.

Then visit the Downloads page and locate the version that matches the one you need.

Click the JDK Download button and you’ll be taken to a screen that shows the versions available. Click the package for Linux.

You’ll be presented with a screen asking you to accept the Oracle license agreement. Select the checkbox to accept the license agreement and press the Download button. Your download will begin. You may need to log in to your Oracle account one more time before the download starts.

Once the file has downloaded, you’ll need to transfer it to your server. On your local machine, upload the file to your server. On macOS, Linux, or Windows using the Windows Subsystem for Linux, use the command to transfer the file to the home directory of your user. The following command assumes you’ve saved the Oracle JDK file to your local machine’s folder:

Once the file upload has completed, return to your server and add the third-party repository that will help you install Oracle’s Java.

Install the package, which adds the command to your system:

Next, import the signing key used to verify the software you’re about to install:

You’ll see this output:

Then use the command to add the repo to your list of package sources:

You’ll see this message:

Press to continue the installation. You may see a message about , but you can safely ignore this.

Update your package list to make the new software available for installation:

The installer will look for the Oracle JDK you downloaded in . Create this directory and move the Oracle JDK archive there:

Finally, install the package:

The installer will first ask you to accept the Oracle license agreement. Accept the agreement, then the installer will extract the Java package and install it.

Now let’s look at how to select which version of Java you want to use.

Managing Java

You can have multiple Java installations on one server. You can configure which version is the default for use on the command line by using the command.

This is what the output would look like if you’ve installed both versions of Java in this tutorial:

Choose the number associated with the Java version to use it as the default, or press to leave the current settings in place.

You can do this for other Java commands, such as the compiler ():

Other commands for which this command can be run include, but are not limited to: , and .

Setting the Environment Variable

Many programs written using Java use the environment variable to determine the Java installation location.

To set this environment variable, first determine where Java is installed. Use the command:

This command shows each installation of Java along with its installation path:

In this case the installation paths are as follows:

1. OpenJDK 11 is located at
2. Oracle Java is located at .

Copy the path from your preferred installation. Then open using or your favorite text editor:

At the end of this file, add the following line, making sure to replace the highlighted path with your own copied path, but do not include the portion of the path:

Modifying this file will set the path for all users on your system.

Save the file and exit the editor.

Now reload this file to apply the changes to your current session:

Verify that the environment variable is set:

You’ll see the path you just set:

Other users will need to execute the command or log out and log back in to apply this setting.

Conclusion

In this tutorial you installed multiple versions of Java and learned how to manage them. You can now install software which runs on Java, such as Tomcat, Jetty, Glassfish, Cassandra or Jenkins.

Introduction

Java and the JVM (Java’s virtual machine) are required for many kinds of software, including Tomcat, Jetty, Glassfish, Cassandra and Jenkins.

In this guide, you will install various versions of the Java Runtime Environment (JRE) and the Java Developer Kit (JDK) using . You’ll install OpenJDK as well as official packages from Oracle. You’ll then select the version you wish to use for your projects. When you’re finished, you’ll be able to use the JDK to develop software or use the Java Runtime to run software.

Prerequisites

To follow this tutorial, you will need:

Installing the Default JRE/JDK

The easiest option for installing Java is to use the version packaged with Debian. By default, Debian 9 includes Open JDK, which is an open-source variant of the JRE and JDK.

This package will install OpenJDK version , which is compatible with Java 8. Java 8 is the current Long Term Support version and is still widely supported, though public maintenance ends in January

To install this version, first update the package index:

Next, check if Java is already installed:

If Java is not currently installed, you’ll see the following output:

Execute the following command to install OpenJDK:

This command will install the Java Runtime Environment (JRE). This will allow you to run almost all Java software.

Verify the installation with:

You’ll see the following output:

You may need the Java Development Kit (JDK) in addition to the JRE in order to compile and run some specific Java-based software. To install the JDK, execute the following command, which will also install the JRE:

Verify that the JDK is installed by checking the version of , the Java compiler:

You’ll see the following output:

Next, let’s look at how to install Oracle’s official JDK and JRE.

Installing the Oracle JDK

If you want to install the Oracle JDK, which is the official version distributed by Oracle, you’ll need to add a new package repository for the version you’d like to use.

First, install the package which adds the command which you’ll use to add additional repositories to your sources list.

Install with:

With this installed, you can install Oracle’s Java.

Installing Oracle Java 8

To install Java 8, which is the current long-term support version, first add its package repository:

When you add the repository, you’ll see a message like this:

Press to continue. It will attempt to import some GPG signing keys, but it won’t be able to find any valid ones:

Execute the following command to add the GPG key for the repository source manually:

Then update your package list:

Once the package list updates, install Java 8:

Your system will download the JDK from Oracle and ask you to accept the license agreement. Accept the agreement and the JDK will install.

Installing Oracle Java 10

To install Oracle Java 10, first add its repository:

You’ll see this message:

Press to continue the installation. Like with Java 8, you’ll see a message about invalid signing keys:

Execute this command to import the necessary key:

Then update your package list:

Once the package list updates, install Java

Your system will download the JDK from Oracle and ask you to accept the license agreement. Accept the agreement and the JDK will install.

Now let’s look at how to select which version of Java you want to use.

Managing Java

You can have multiple Java installations on one server. You can configure which version is the default for use on the command line by using the command.

This is what the output would look like if you’ve installed all versions of Java in this tutorial:

Choose the number associated with the Java version to use it as the default, or press to leave the current settings in place.

You can do this for other Java commands, such as the compiler ():

Other commands for which this command can be run include, but are not limited to: , and .

Let’s set the environment variable next.

Setting the Environment Variable

Many programs written using Java use the environment variable to determine the Java installation location.

To set this environment variable, first determine where Java is installed. Use the command again:

This command shows each installation of Java along with its installation path:

In this case the installation paths are as follows:

• Oracle Java 10 is located at .
• Oracle Java 8 is located at .
• OpenJDK 8 is located at .

These paths show the path to the executable.

Copy the path for your preferred installation, excluding the trailing component. Then open using or your favorite text editor:

At the end of this file, add the following line, making sure to replace the highlighted path with your own copied path:

Modifying this file will set the path for all users on your system.

Save the file and exit the editor.

Now reload this file to apply the changes to your current session:

Verify that the environment variable is set:

You’ll see the path you just set:

Other users will need to execute the command or log out and log back in to apply this setting.
