NAME

java-pkg-simple.eclass - Eclass for packaging Java software with ease.

DESCRIPTION

This class is intended to build pure Java packages from Java sources without the use of any build instructions shipped with the sources. There is no support for generating source files, or for controlling the META-INF of the resulting jar, although these issues may be addressed by an ebuild by putting corresponding files into the target directory before calling the src_compile function of this eclass.

FUNCTIONS

java-pkg-simple_src_compile: src_compile for simple bare source java packages. Finds all *.java sources in ${JAVA_SRC_DIR}, compiles them with the classpath calculated from ${JAVA_GENTOO_CLASSPATH}, and packages the resulting classes to a single ${JAVA_JAR_FILENAME}. If the file target/META-INF/MANIFEST.MF exists, it is used as the manifest of the created jar.
If USE FLAG 'binary' exists and is set, it will just copy ${JAVA_BINJAR_FILENAME} to ${S} and skip the rest of src_compile.
java-pkg-simple_src_install: src_install for simple single jar java packages. Simply installs ${JAVA_JAR_FILENAME}. It will also install a launcher if ${JAVA_MAIN_CLASS} is set. Also invokes einstalldocs.
java-pkg-simple_src_test: src_test for simple single java jar file. It will compile test classes from test sources using ejavac and perform tests with frameworks that are defined in ${JAVA_TESTING_FRAMEWORKS}. test-classes compiled with alternative compilers like groovyc need to be placed in the "generated-test" directory as content of this directory is preserved, whereas content of target/test-classes is removed.

ECLASS VARIABLES

JAVA_GENTOO_CLASSPATH

Comma or space separated list of java packages to include in the class path. The packages will also be registered as runtime dependencies of this new package. Dependencies will be calculated transitively. See "java-config -l" for appropriate package names.

        JAVA_GENTOO_CLASSPATH="foo,bar-2"

JAVA_GENTOO_CLASSPATH_EXTRA

Extra list of colon separated path elements to be put on the classpath when compiling sources.

JAVA_CLASSPATH_EXTRA

An extra comma or space separated list of java packages that are needed only during compiling sources.

JAVA_NEEDS_TOOLS

Add tools.jar to the gentoo.classpath. Should only be used for build-time purposes, the dependency is not recorded to package.env.

JAVA_SRC_DIR

An array of directories relative to ${S} which contain the sources of the application. If you set ${JAVA_SRC_DIR} to a string it works as well. The default value "" means it will get all source files inside ${S}. For the generated source package (if source is listed in ${JAVA_PKG_IUSE}), it is important that these directories are actually the roots of the corresponding source trees.

        JAVA_SRC_DIR=( "impl/src/main/java/"
                "arquillian/weld-ee-container/src/main/java/"
        )

JAVA_RESOURCE_DIRS

An array of directories relative to ${S} which contain the resources of the application. If you do not set the variable, there will be no resources added to the compiled jar file.

        JAVA_RESOURCE_DIRS=("src/java/resources/")

JAVA_ENCODING ?= UTF-8

The character encoding used in the source files.

JAVAC_ARGS

Additional arguments to be passed to javac.

JAVA_MAIN_CLASS

If the java has a main class, you are going to set the variable so that we can generate a proper MANIFEST.MF and create a launcher.

        JAVA_MAIN_CLASS="org.gentoo.java.ebuilder.Main"

JAVA_AUTOMATIC_MODULE_NAME

The value of the Automatic-Module-Name entry, which is going to be added to MANIFEST.MF.

JAVADOC_ARGS

Additional arguments to be passed to javadoc.

JAVA_JAR_FILENAME ?= ${PN}.jar

The name of the jar file to create and install.

JAVA_BINJAR_FILENAME

The name of the binary jar file to be installed if USE FLAG 'binary' is set.

JAVA_LAUNCHER_FILENAME

If ${JAVA_MAIN_CLASS} is set, we will create a launcher to execute the jar, and ${JAVA_LAUNCHER_FILENAME} will be the name of the script.

JAVA_TESTING_FRAMEWORKS

A space separated list that defines which tests it should launch during src_test.

JAVA_TESTING_FRAMEWORKS="junit pkgdiff"

JAVA_TEST_RUN_ONLY

A array of classes that should be executed during src_test(). This variable has precedence over JAVA_TEST_EXCLUDES, that is if this variable is set, the other variable is ignored.

JAVA_TEST_RUN_ONLY=( "net.sf.cglib.AllTests" "net.sf.cglib.TestAll" )

JAVA_TEST_EXCLUDES

A array of classes that should not be executed during src_test().

JAVA_TEST_EXCLUDES=( "net.sf.cglib.CodeGenTestCase" "net.sf.cglib.TestAll" )

JAVA_TEST_GENTOO_CLASSPATH

The extra classpath we need while compiling and running the source code for testing.

JAVA_TEST_SRC_DIR

An array of directories relative to ${S} which contain the sources for testing. It is almost equivalent to ${JAVA_SRC_DIR} in src_test.

JAVA_TEST_RESOURCE_DIRS

It is almost equivalent to ${JAVA_RESOURCE_DIRS} in src_test.
