Java is programming language and runtime environment. You can use Zero Install to:

• Get Java development tools and SDKs
• Run apps that need Java as a dependency

To get the traditional Java commands: 0install add java https://apps.0install.net/java/jre.xml 0install add javac https://apps.0install.net/java/jdk.xml

The other tools are available by passing the tool name as a --command option to 0install add, e.g.:

To get common Java build tools: 0install add ant https://apps.0install.net/java/ant.xml 0install add mvn https://apps.0install.net/java/maven.xml 0install add gradle https://apps.0install.net/java/gradle.xml

To use the Java Runtime Environment as the runner in a feed:
<command name="run" path="myapp.jar"> <runner interface="https://apps.0install.net/java/jre.xml"/> <arg>-jar</arg> </command>

If you wish to use the CLASSPATH variable to specify external dependencies in a feed you can use JAR Launcher:
<command name="run" path="myapp.jar" /> <runner interface="https://apps.0install.net/java/jar-launcher.xml"/> </command> <environment name="CLASSPATH" insert="myapp.jar"/> <requires interface="http://example.com/mylib.xml"> <environment name="CLASSPATH" insert="mylib.jar"/> </requires>
