native-maven-plugin does not work with Eclipse Maven workspace resolution:
"Unable to copy dependency to staging area"
----------------------------------------------------------------------------------------------------------------------
Key: MOJO-1535
URL: http://jira.codehaus.org/browse/MOJO-1535
Project: Mojo
Issue Type: Bug
Environment: linux-x86-64, sun jdk 1.6.0_20, eclipse with maven2 plugin
Reporter: Peter De Maeyer
Affects: native-maven-plugin, version 1.0-alpha-5.
I have a project combining some java code and native code through jni.
When running maven "install" target from within eclipse, the linker fails with
"Unable to copy dependency to stating area".
The reason seems to be that the NativeLinkMojo receives a directory as artifact
rather than a .jar, and fails on it.
That is of course precisely what workspace resolution is all about: it uses
directories in the workspace instead as artifacts instead of .jars. It's a
perfectly valid use case, and plugins should be able to deal with it.
Note that #MOJO-820 is about a similar problem, and is marked as "won't fix",
but I suggest you reconsider in the context of this new use case.
