jh_build - compile java sources in the absence of a (useful) upstream build system

jh_build [debhelper options]

jh_build [debhelper options] jarfile source [... source]

A file consisting of each build to perform. One build per line where each line consists of:

jarfile source [... source]

Where jarfile is the name of the jar file to be built and source is a source file or directory containing source files.

Set the Main-Class attribute in the manifest of the generated jar file(s) to main-class. This makes java -jar generated-jar-file run that class.
Use home as JAVA_HOME (overrides the JAVA_HOME environment variable).
Whether or not to build javadoc for the jar files. The default is to generate javadoc along with the jar files.
Pass options to javac (when invoking javac). The options value is a space-separate list of options (remember to quote the argument to avoid the shell interpreting the value).
Pass options to javadoc (when invoking javadoc). The options value is a space-separate list of options (remember to quote the argument to avoid the shell interpreting the value).
If passed, jh_build will clean up after itself. This is called by jh_clean(1) and using jh_clean(1) is recommended over calling jh_build with --clean directly.

If set (and --java-home is omitted), it determines the location of the java home for finding the javac(1) compiler, javadoc(1) compiler and the jar(1) utility.

If the environment variable is unset and --java-home is omitted, then the default java home is /usr/lib/jvm/default-java

If set, this is the classpath used during compilation of the source code.
A space separated list of extra files or directories to include in the generated jar file(s).

Can be omitted if no extra files need to be included.

  jh_build foo.jar src/java/main

Will generate foo.jar from compiling all the java files in src/java/main and generate a javadoc from it.
