Re: [m2e-users] up to date resources for m2e with Eclipse / RAD
So, after this is settled up, the question - what are the connectors good for and any advices / suggestions when to use them. I'm in particular puzzled by the buildhelper and m2e-jdt-plugins - what exactly they are doing and should they be always used. I mean, we don't have any problems with our current maven builds neither in eclipse nor outside it, but as far as I got it correct these connectors should interact b/n m2e and eclipse in order to avoid potential problems arising from the incremental builds in eclipse such as endless loops or memory leaks, etc. Any help will be much appreciated!

TIA,
Ilko

Hi and thanks for all the answers!

Sorry for the late reply, but I wanted to double check again everything with fresh workspace / svn co, etc., because the issue was specific to particular client. At last I found out that we are hitting this maven issue:

https://jira.codehaus.org/browse/MJAR-156

The provided workaround seems to fix the problem for now and I hope that it won't cause another hidden problem :-(.

Special thanks to Marcel, who provided great info about the internals of the WAS TE deployment - these details brought me to the root of the problem!

The versions we are using, if of interest:

RAD Version: 8.5.0
Build ID: RADO85-I20120529_2348

m2e - Maven Integration for Eclipse    1.2.0.20120903-1050    org.eclipse.m2e.feature.feature.group
m2e-wtp - Maven Integration for WTP (Incubation)    0.16.0.20120914-0945    org.eclipse.m2e.wtp.feature.feature.group
m2e - slf4j over logback logging (Optional)    1.2.0.20120903-1050    org.eclipse.m2e.logback.feature.feature.group
m2e connector for mavenarchiver pom properties    0.15.0.201207090125-signed-201209140800    org.sonatype.m2e.mavenarchiver.feature.feature.group

WAS: 8.5.0.0

OS: Windows 7 professional 64-bit

Thanks again to all of you!

Hi Ilko,

For me, tracing the path through the following config files helped me learn alot about the way RAD and WAS work together:

- <RAD home>\runtimes\base_v7\profiles\<profile>\config\cells\<cell>\applications\<application>.ear\deployments\<application>\deployment.xml
- this file contains a property 'was.loose.config' which points to a 'looseconfig.xmi' file inside the .metadata of your RAD workspace
- this looseconfig.xmi contains a self explanatory description of your EAR in exploded form: every module or jar is represented by a tag which has a 'binariesPath' attribute.
- this binariesPath points to either a directory containing for instance the compiled classes or to a packaged jar or module.

The RAD servers view lets you select the deployment style (run with resources in workspace, etcetera) which influences the way in which the above setup is used: run with resources on server will obviously not make use of the looseconfig.xmi pointer to your workspace in the deployment.xml

The above describes the situation from a WAS point of view. M2Eclipse and RAD/EclipseWTP work together to create these configs from your pom.xml and the all important '.settings/org.eclipse.wst.common.component'

Hi Marcel,

Thanks for your input - the link in 1 is known to me - that was our first guide how to correctly intall m2e in RAD 8.5. However, it is missing advanced explanations how the resources are resolved in workspace, etc. Regarding 2, we are still on the "pure" RAD front because of the current licence situation. I'll search the threads about your posts - thanks for the info!

Hi Ilko,

Some time ago I've posted a few times about my findings when using m2eclipse with RAD. Search the archives to find more. One link I could recover easily is [1]. Just as a suggestion, did you also consider using Websphere Developer Tools [2] ?

Regards, Marcel

Hi,

can someone point me to up to date resources about the maven eclipse
integration (if something specifical to RAD 8.5 is available would be
great). I'm interested to get relative  deep knowledge about the
integration between the maven and eclipse as provided by the m2e plugin
- ways to resolve dependencies, to perform builds, what gets reflected
by turning on / off different m2e / classpath related options, what are
the connectors good for etc. Of particular interest could be also what
are the preferred settings for ignored resources for SCM. Of course, RAD
/ WAS TE specifical docs will be great if available.

TIA,
Ilko
