Description

« Hide

It would make maven2 more "GNU Classpath" friendly if there is less flexibility in maven 2 bootstraping ode.
For example in maven-mboot2/src/main/java/compile/JavacCompiler.java, the class "com.sun.tools.javac.Main" is hardcoded. This result in a NullPointerException when trying to build maven2 with GCJ.

shouldn't GCJ implement that class? AFAIK that is the standard API for accessing a javac-like compiler.

Anyway, we should definitely have other alternatives in the bootstrap. We could probably download the plexus compilers we use instead of having one hardcoded in the bootstrap

Damien: I have a set of tools that builds Maven 2 with free tools only. I haven't use any of the GNU tools, only the java-based ones but it shouldn't be hard adding support for GCJ and co. I can publish these somewhere if there's an interest in that.

Brett: The biggest issue with the MBoot for the Linux distros is that it's downloading stuff of the internet which is not something that builds are allowed to do. I have a technique in my scripts that basically builds everything (including dependencies) from source.

Brett: Not that downloading the implementation isn't useful

We will build and test against released and certified JDKs, trying to support all variants of GJC is untentable.
