As
far as I know, the proper way to provide build-before-launch
behaviour is by implementing
ILaunchConfigurationDelegate2.buildForLaunch. Unfortunately this
requires new launch configuration type and won't work for standard
RunAs->JavaApplication and similar.
ILaunchListener API does not seem to allow for long-running operations,
i.e. no IProgressMonitor is passed in. You should still be able to run
your goals from ILaunchListener.launchAdded... but this will be a hack
in my opinion.
What goal do you want to execute? Maybe I can suggest alternative
approach.

2) I guess the logic in m2e extension would be:
* get current list of ILaunchConfiguration from ILaunchManager;
* subscribe itself as ILaunchListener;
* when launch event is fired: get current ILaunch, find main(...)
class from ILaunch;
* find all workspace open maven projects that main() project
depends on;
* run maven goals in these projects;
* allow launch to proceed;
do you think this is feasible?
Thank you,
Andrei

Hello;
1) I am developing a m2e extension on the lines of:
http://wiki.eclipse.org/M2E_Extension_Development
2) In need to cover 2 executions:
a) http://felix.apache.org/site/apache-felix-maven-scr-plugin-use.html
org.apache.felix:maven-scr-plugin:scr
b)
http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html
org.apache.felix:maven-bundle-plugin:manifest
QUESTIONS:
A) I need to run both of the above goals right before java
application launch via eclipse launcher;
(I do not want to run them on incremental build)
how m2e gives access to "build-before-launch" JDT event?
Can you provide some documentation pointers or other information that
explains how to implement build-before-launch "handler"?
B) if there is no m2e access to
"build-before-launch" JDT event,
can I run these goals on background, in async thread pool w/o
blocking m2e builder invocation?
(so incremental build just serves as a trigger for background rebuild)
This really depends on what you need to do. If your project
configurator
needs access to workspace, especially change any workspace resources,
it
will likely be easier to run this code as part of a builder. If the
code
does not make any changes to workspace, it is probably be okay to run
this as a background job.
C) maven-bundle-plugin life cycle is
already mapped by some other
m2e extension;
(I receive "conflicting life cycle mappings" error)
how can I override that? how can I find which other extension is
doing that?
m2e-tycho provides mapping for maven-bundle-plugin bundle and manifest
goals. Either uninstall m2e-tycho project configurator or force use of
your project configurator from pom.xml file.
