| ## Category |
| |
| Test (Compile) |
| |
| ## Description |
| |
| Provides support for [Java](https://java.net) compilation. |
| |
| The location of Java must be configured either via the command line (--) or via the `JAVA_HOME` environment variable. On Mac OS X, `/usr/libexec/java_home` may also be used. |
| |
| The `JAVA_HOME`/`--java-home` JDK is considered the base JDK and will always be used last when `--multijdk` options are used. Therefore, it should **always** be the earliest version so that bytecode remains compatible between versions. |
| |
| ## Environment Variables |
| |
| `JAVA_HOME` may be used to set the location of the JDK. |
| |
| ## Options |
| |
| | Option | Notes | |
| | :--------------------------------- | :---------------------------------------------------------------------------------------------------- | |
| | `--java-home` | The base JDK to use for Java work | |
| | `--multijdkdirs=<dir1,dir2,..>` | Comma delimited list of directories to treat as JDKs | |
| | `--multijdktests=<test1,test2,..>` | Comma delimited list of tests that support MultiJDK mode that should actually be run in MultiJDK mode | |
| |
| ## Docker Notes |
| |
| Locations should be local to the Docker container image. |
| |
| ## Developer Notes |
| |
| * Options are actually handled by `test-patch` directly due to intertwined nature of them. |
