# Class JavaBasePlugin

java.lang.Object
org.gradle.api.plugins.JavaBasePlugin

All Implemented Interfaces:
  `Plugin<Project>`

public abstract class JavaBasePlugin extends Object implements Plugin<Project>

A `Plugin` which compiles and tests Java source, and assembles it into a JAR file.

This plugin is automatically applied to most projects that build any JVM language source. It creates a `JavaPluginExtension` extension named `java` that is used to configure all jvm-related components in the project. It is responsible for configuring the conventions of any `SourceSet`s that are present and used by (for example) the Java, Groovy, or Kotlin plugins.

  - ### COMPILE_CLASSPATH_PACKAGING_SYSTEM_PROPERTY

    public static final String COMPILE_CLASSPATH_PACKAGING_SYSTEM_PROPERTY
    Set this property to use JARs build from subprojects, instead of the classes folder from these project, on the compile classpath. The main use case for this is to mitigate performance issues on very large multi-projects building on Windows. Setting this property will cause the 'jar' task of all subprojects in the dependency tree to always run during compilation.
