Re: [m2e-dev] m2e classloader made from MavenProject.getCompileClasspathElements()?
|
You did not explain what is your final goal, i.e. user-visible behaviour
you want to implement. Are you trying to execute the code from workspace
projects or do something else with the classes? Generally, I would not
recommend running workspace code inside Eclipse JVM and I would
certainly avoid classloaders is a way to do workspace resources lookup,
for example, but your situation may be different.

I am sorry, but I only answer m2e development questions on
m2e-dev@xxxxxxxxxxx mailing list.

What are you trying to achieve?
in m2e examples I found, m2e instantiates new ProjectConfigurator on
every incremental build invocation;
in the spirit of getting minimum response time, I would like to cache
class loaders
for "stable" dependencies (like those coming from jars and not from
folders)
Neither m2e inside Eclipse workspace nor maven on command line create
classloaders for project compile classpath but there may be other ways
to achieve what you need.
so my request then is a bad idea? :-)

*Igor, hello:*
currently I am duplicating your m2e classloader; can you please
clarify:
1) where can I get m2e classloader made from
MavenProject.getCompileClasspathElements()?
(and also test class path elements?)
I can not see it in any of:
final IMaven maven = MavenPlugin.getMaven();
final BuildContext buildContext = getBuildContext();
final MavenSession session = getSession();
final MojoExecution execution = getMojoExecution();
final MavenProject project = session.getCurrentProject();
2) is this classloader auto-updated on maven pom.xml change?
if not, how can I force an update?
the intent is to load newly incrementally built
target/classes/com/example/SomeComponent.class
and do some byte instrumentation on it,
while having access to m2e-already-resolved compile (or test) scope;
Thank you,
Andrei.
