Gradle Java Cross-Compile Plugin

Automatically configures the bootstrap classpath when the requested targetCompatibility is less than the current Java version, avoiding:

warning: [options] bootstrap class path not set in conjunction with -source 1.7

The plugin supports Java, Groovy joint compilation, and Kotlin. The plugin locates JDKs via either:

• Environment variables
  • In the form JDK1x where x is the major version, for instance JDK18 for Java 8
• Default installation locations for MacOS, Ubuntu and Windows
  • Where more than one version of the JDK is available for a given version is available, the highest is used
  • The lookup prefers Oracle JDKs, but falls back to OpenJDK where possible
• SDKMAN! JDK candidates
  • The lookup prefers JDKs with no suffix, then Oracle JDKs then OpenJDK (zulu)
