I have a maven project with 1 parent and 5 modules. One of the modules (call it P) is of packaging "maven-plugin", which is configured to be run in the execution phase "process-test-classes of other module (call it T).
The module T has pom.xml as follows. I omitted dependencies, but they don't include P. As in many other cases it all works perfectly in command line.
Question: Whatever I do Eclipse shows "Could not find artifact org.local.enhancer:pom:0.0.2-SNAPSHOT pom.xml /test line 1 Maven Configuration Problem".
Seems like the issue started after installing "m2e-wtp" v0.17 to resolve other issue with offending jars. Configuration is Eclipse Juno SR2, m2e v1.3.1, m2e-wtp v0.17.

Does anybody have any insight on this? Thanks!

Am creating new java project using the pom.xml file. when i run the command mvn clean install am getting build failure error.
Can anyone please help me to resolve this issue.

Maven Central doesn't seem to have a 3.3.9 build for maven-compiler-plugin (see here). Regardless, the 3.3 generation is quite old. Unless you absolutely, positively have to use such an old version, just move forward to a newer version that actually exists, like 3.6.0, and you should be fine.

I want to use m2eclipse with m2e-wtp to deploy this project to Glassfish 3. However, m2e-wtp does not deploy the dependencies. I know that building superjars with jar-with-dependencies is probably not the way to go for EJB projects, but I cannot really change this without messing up the customer's build / deployment processes.
So, the problem is that the deployment assembly wizard does not display the maven dependencies:
I need a solution that works without changing the pom.xml, since that would disturb the customer's build processes. I am aware that using an EAR would be the preferred solution here.
Is the behaviour that I'm seeing a bug or is it an inherent limitation in the way m2e-wtp and the ejb packaging work?
Is it even possible to have m2e-wtp extract dependency jars into the deployed application?
In IntelliJ, I created a blank Maven project, and added to pom.xml:
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-compiler</artifactId>
<version>2.11.0-M3</version>
<scope>compile</scope>
</dependency>
I then went to Project Settings -> Modules -> + -> Scala, and specified the compiler jar from the drop-down menu as Maven: org.scala-lang:scala-compiler:2.11.0-M3. I receive the error:
Compiler library: no scala-library*.jar found
Of course, scala-library-2.11.0-M3.jar is among the dependencies (transitively), but not stored in the same folder as scala-compiler-2.11.0-M3.jar, which is what seems to be confusing the Scala plugin.
Is there any way to use scala-compiler*.jar downloaded from a pom.xml dependency? Perhaps by manually specifying where to find each JAR?
Before this, I had been using scala-compiler*.jar downloaded via Project Settings -> Libraries -> + -> From Maven. This seems to work because IntelliJ sticks all the downloaded JARs in the same folder, which is what the Scala plugin assumes. Simply for aesthetic reasons I would like to know if it can be done with pom.xml.
You don't need the scala-compiler as a dependency to be able to build the scala project (neither using maven at command line nor by building from Build | Make Project in IntelliJ).
This is a very simple pom.xml that I use for scala projects where I don't have scala installed at all and just point IntelliJ to this pom and then I can compile and run any scala code directly from within IntelliJ.

I'm trying to compile LESS CSS files with lesscss-maven-plugin, both in pure maven (with command line) and within Eclipse (Juno).
In the lesscss-maven-plugin, I need to define an output directory, but I noticed that in Eclipse WTP copies files from target/m2e-wtp in my server (JBoss), but that this directory is ignored by the war plugin of Maven.
I succeeded to reach my goal with Maven profiles : in Eclipse I use a m2e profile configured in Project settings, so I can define two different destination folders depending on I build in Eclipse or not.
Here is my pom.xml :

This works, but is there a better way to do this, without the profile trick ?
I found another solution with a different less compiler : wro4j. With this compiler, both exists maven and m2e plugins.
In addition, a tutorial (for building boostrap) can be found here: m2e-wro4j
The same solution you provided, a bit cleaner :
https://github.com/marceloverdijk/lesscss-maven-plugin/issues/8
The m2e profile is activated with a m2e variable, so you don't have to select it.
I installed m2eclipse plugin in my eclipse.I have a java project in eclipse. Then I add a pom.xml into the root folder of my project. Convert my project into maven project. Now the problem comes: I can download jar contained in pom.xml, but can't import it into my java file.
Always got java compile error in my project. In package explorer view,I can see maven dependencies.
I have tried this:maven clean, restart eclipse, project clean.

One possibility could be the package/class what you are trying to import is not available in the version of the jar file you have mentioned in the pom.xml.
