JH_COMPILEFEATURES(1) Javahelper JH_COMPILEFEATURES(1) NAME
jh_compilefeatures - Compiles eclipse features using pde-build. SYNOPSIS
jh_compilefeatures [debhelperoptions] [options] [--pde-build-dir=dir] [feature[...]] DESCRIPTION
jh_compilefeatures is a javahelper program that handles compiling features using pde-build. These features can be specified either in debian/eclipse.features or via command-line. jh_compilefeatures uses debhelper behind the scenes and are therefore subject to the compat level (e.g. when parsing the eclipse.features file). When specifying the dependencies for a feature, jh_compilefeatures will see if this feature has just been compiled and will use the dependency if it is among the results. This can be used together with debian/eclipse.features. Dependencies are always resolved by first checking if it is a recently built feature and if not, then the system installed eclipse's dropins folders will be checked. Currently jh_compilefeatures do not clean up between builds, which means the dependencies for previous builds are present for the current build. Nevertheless, do not rely on this, as this behavior is subject to change. Note: jh_compilefeatures will not rearrange the build order for you in order to do this. Note: that jh_compilefeatures will not error out if it cannot find a missing dependency. This is due to the underlying builder being unable to detect this. FILES
debian/eclipse.features List the eclipse features to compile and their dependencies. The first item on the line is the feature to compile and the following items are considered dependencies. A dependency can either be a dropins folder or a previous built feature. jh_compilefeatures will find it as long as it is installed in the system eclipse's dropins folder or it has just been compiled. OPTIONS
--pde-build-dir=dir Specifies the directory from where pde-build is to be run. Defauls to "debian/.eclipse_build". --feature-deps=deps A space separated list of dependencies. These dependencies will be used to compile all features passed by command-line. Features read from debian/eclipse.features are unaffected by this. --build-opts=args Pass args to the underlying builder. These options are passed to all features built. This defaults to "-DjavacTarget=1.5 -DjavacSource=1.5" if not set. This can be disabled by passing the empty string. --jvm-args=args Pass args to the JVM. These options are passed to all features built. --orbit-dir=dir Specifies where the Orbit dependencies can be found. This is only needed if the orbit dir is in an unusual location. --pde-build=cmd Use a non-standard pde-build command to compile the features. --pde-args=args Passes args directly to pde-build. Note, jh_compilefeatures have specialised options for some of pde-build options and these should be used whenever possible. These options are passed to all features built. --ignore-java-home Skip the check of JAVA_HOME. Since the underlying builder uses ant (and therefore java), the build should ensure it always uses the expected java implementation. Use this if you (for whatever reason) need to declare the specific java implementation without being able to use JAVA_HOME. Note: You still have to tell the underlying builder which java to use. EXAMPLE
A sample debian/eclipse.features org.eclipse.tm.terminal emf org.eclipse.rse.sdk org.eclipse.tm.terminal depends on "emf", which is expected to be found in eclipse's dropins folder. org.eclipse.rse.sdk on the other hand has no dependencies beyond the eclipse platform. If needed you can also specify a previously built feature as a dependency: org.eclipse.some.feature org.eclipse.another.feature org.eclipse.some.feature rse Here org.eclipse.another.feature depends org.eclipse.some.feature, which was just built and also rse, which is expected to be in system installed eclipse's dropins.
