m2e-scala sample projects errors - Plugin execution not covered by lifecycle configuration

[Francois]

Hello,

I tried to import m2eclipse-scala sample projects available on
https://github.com/sonatype/m2eclipse-scala/tree/master/samples in
Eclipse Indigo, with Eclipse-IDE 2.0.0-beta8, m2e
1.0.0.20110607-2117 and m2e-scala 0.3.0 installed.

When importing prj-custom-layout and prj-scala-cycle-java , I see the
dreaded "Plugin execution not covered by lifecycle configuration:
org.scala-tools:maven-scala-plugin:2.13.1:add-source (execution:
scala-compile-first, phase: process-resources)"

Adding the following in the pom.xml <build> section remove the error
message, but I understood that it was not what is expected:

<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.scala-tools</groupId>
<artifactId>maven-scala-plugin</artifactId>
<versionRange>[0.1,)</versionRange>
<goals>
<goal>add-source</goal>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</pluginExecutionFilter>
<action>
<configurator>
<id>org.maven.ide.eclipse.scala</id>
</configurator>
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>

Hope it helps,

Given that the sample pom.xml is broken, what's the proper way to do mixed Java/Scala projects with m2eclipse-scala currently?

One project for Scala, one project for Java. Forget mixed Scala/Java in a
single project unless you want to lose a couple of months of developer time.

Just adding the <pluginManagement> from my other mail made it work for us. We do have a mixed Java/Scala project, and all seems OK.

Bryan, thanks for your clear answer (and stopping me while I had only
wasted a few hours). :)

I'll follow your advice and wait for things to shake up with Scala IDE
before trying again.

Hi,

I deployed version 0.3.1 of m2eclipse-scala that should avoid the "workaround of pollute" you pom.xml with <lifecycleMappingMetadata>.

I also update the sample project to use scala 2.9.0-1 and maven-scala-plugin 2.15.2.

To test, I setup a similar eclipse : an Indigo with ScalaIDE 2.0.0beta9 (my first install of serie 2.x.x ;-) ), the latest m2e

I successfully install samples, included mixed Java/Scala sample, but sometimes I need to call "Maven > Update Project Configuration..." after import.

Thanks David, I will test that in a near future. And I'm quite happy
that you found some time to work again on all that stuff of yours, I'm
daily grateful for all of it.

Thanks,

I had the same issue with the following pom.xml, which Eclipse's m2e patched as you can see, to prevent the issue. the maven project builds just fine with the scala tests. Is there any better way?
