Eclipse version: 2022-09
Eclipse m2e version: 2.0.4
antlr version: 3
antlr3-maven-plugin: 3.5.3
I have a project with a Logic.g file. Everything was working OK on a previous version of Eclipse (where I had installed an m2e antlr connector), meaning the file would be converted to target/generated-sources/antlr3 (LogicLexer.java and LogicParser.java), and somehow be picked up by Eclipse and compile a Logic.tokens file in target, and the LogicLexer.class and LogicParser.class within target.
In Eclipse 2022-09 however, my test classes that use either LogicLexer or LogicParser yield a compilation error in Errors "cannot be resolved to a type".
It's just a problem in Eclipse (nothing changed in the code, and a maven verify works correctly).
The tokens file and the .class are being generated as long as I have the lifecycleMappingMetadata configured (see snippet below).
Question: How can I make the Eclipse project see these compiled classes and remove the compilation errors?

I am using Eclipse Juno with Maven 3.0.5 on Windows 7. The project was previously on Windows XP and I have moved to Windows 7 64 bit machine.
I have copied my Eclipse Spring 3, Hibernate 4 and JSF 2.0 project and when I try to compile I am getting the following error
Plugin execution not covered by lifecycle configuration:
org.bsc.maven:maven-processor-plugin:2.0.6:process (execution: process, phase:
generate-sources)
I tried as mentioned in this thread by adding the following in Eclipse.ini file, however it didn't solve the issue.
-vm
c:\Program Files\Java\jdk1.7.0_21\jre\bin\server\jvm.dll
Tried building maven install and clean, but problem still persists.
How can I resolve this issue? Any help is highly appreciable.
Thanks

Newer versions of m2e complain if a Maven plugin does not provide a m2e lifecycle mapping. Newer plugins provider such a mapping via the file META-INF/m2e/lifecycle-mapping-metadata.xml in their JAR. If this file is not present, then Eclipse complains.
It is possible quite down these complaints by adding a lifecycle mapping for older plugins to your POM. In the given example, this mapping is done inside a profile which is automatically activated when a build is running in Eclipse (m2e.version property is set) and it is not active when a regular maven build is done.
<profiles>
<profile>
<id>m2e</id>
<activation>
<property>
<name>m2e.version</name>

The example above disables the plugin in Eclipse builds. It is also possible enable it by specifying <execute /> as action .
Mind that the settings under pluginExecutionFilter must match the plugin and the goals of the plugin that you wish to map. Multiple pluginExecution elements can be specified to map different plugins.
I'm importing an existing Maven project for Scala. I'm prompted by Eclipse to "Set up maven plugin connectors" for the plugin "maven-scala-plugin" version 2.13.1 but two goals are highlighted red with no optons support available to select.
What plugins are available to support the compile and testCompile goals?
Eclipse is 3.7.2, but I'm not wedded to this version.
You don't need to support the compile and testCompile goals, the compilation is done by scala-ide. You need to add the following mess to your pom.xml:
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<versionRange>[3.1.0,)</versionRange>
<goals>
<goal>add-source</goal>
<goal>compile</goal>
<goal>testCompile</goal>
<goal>doc</goal>
<goal>doc-jar</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>
This tells your m2e (the maven plugin for eclipse) to ignore the goals which apply to your scala-maven-plugin. You'll have to change the groupId & versionRange as well.
I would like to be able to configure the pom.xml so that when I import it into eclipse it specifies src/main/aspect as an eclipse source folder.
At the moment, importing creates the default source folders but that is all.
What should be done?
Thanks

I have configured the aspectj plugin thus:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<goals>

I have configured the m2e plugin thus:
<plugin>

</pluginExecutionFilter>
<action>

</plugin>
You shouldn't configure the defaults of the plugin, cause it defines already the src/test/aspect and src/main/aspect and it shouldn't be necessary to configuration something supplemental to compile etc.
Furthermore the problem with eclipse could be based on a missing mapping for your m2e plugin this means to add the following to your build:
<pluginManagement>
<plugins>

This might cause you problem in Eclipse not to see the source folder correctly imported.
I believe source is supposed to be a java version, not a directory. Same for target. sources allows you to specify the source directories, and the docs say that if not specified, the java sources of the current project will be used - just one for your project as configured currently.
I would try listing the directories in the sources parameter, and if that didn't work, I'd remove sources and try build-helper:add-source. I'm not sure there's an m2e connector for build-helper-maven-plugin yet so you might have to add a similar mapping to the one khmarbaise mentioned.
I think it would not be added as source folder by Eclipse. you could add it on your own in Java Build Path > Source.
This is not necessary: Then you need to have AJDT plugin installed in and convert the project to AspectJ Project, otherwise the .ajfiles will be full of errors complained by Eclipse. The errors does not affect maven compiling.
In my experience, recognized or not as source would not affect maven compiling the .aj files under src/main/aspect
Both aspectDirectory and aspectTestDirectory have default values as you given. they are not needed if the same as default.
Here below is my pom configuration (didn't try test-compile) and it works:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>

I use a clean eclipse 3.7, then added the Maven Integration for Eclipse from the Eclipse Marketplace. I also added WTP Integration and m2e connector for build-helper-maven-plugin from Windows -> Preferences -> Maven -> Discovery -> Open Catalog. I also added the Google Plugin for Eclipse.
I import an exising maven project that works fine with the command line when running command like: mvn compile gwt:compile or mvn gwt:run but in Eclipse I got this error:

I managed to make it work by adding
-vm
C:\Program Files\Java\jdk1.6.0_26\jre\bin\server\jvm.dll
before -vmargs in eclipse.ini
As a rule of thumb you always need to change default JRE under Window->Preferences->Java->Installed JREs to JDK folder. In my case it was C:\Program Files\Java\jre6. I had to change it to C:\Program Files\Java\jdk1.6.0_31
I had the same problem on a Linux environment, I did the same thing Sydney did above but I still had to disable incremental build for maven processor, like this:
...
<action>
<execute>
<runOnIncremental>false</runOnIncremental>
</execute>
</action>
...
This worked for me :)
I have a fairly simple Maven project:
<project>
<dependencies>
...
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/dependencies</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
However, I get the following error in m2eclipse:
Description Resource Path Location Type
maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e. pom.xml /jasperreports-test line 60 Maven Project Build Lifecycle Mapping Problem
Why do I care if m2eclipse doesn't "support" this task? Maven does, and that's all I really care about. How can I get this error in my project to go away?
It seems to be a known issue. You can instruct m2e to ignore this.
Option 1: pom.xml
Add the following inside your <build/> tag:
<pluginManagement>
<plugins>
<!-- Ignore/Execute plugin execution -->
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<!-- copy-dependency plugin -->
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<versionRange>[1.0.0,)</versionRange>
<goals>
<goal>copy-dependencies</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins></pluginManagement>
You will need to do Maven... -> Update Project Configuration on your project after this.
Read more: http://wiki.eclipse.org/M2E_plugin_execution_not_covered#m2e_maven_plugin_coverage_status
Option 2: Global Eclipse Override
To avoid changing your POM files, the ignore override can be applied to the whole workspace via Eclipse settings.
Save this file somewhere on the disk: https://gist.github.com/maksimov/8906462
In Eclipse/Preferences/Maven/Lifecycle Mappings browse to this file and click OK:
This is a problem of M2E for Eclipse M2E plugin execution not covered.
To solve this problem, all you got to do is to map the lifecycle it doesn't recognize and instruct M2E to execute it.
You should add this after your plugins, inside the build. This will remove the error and make M2E recognize the goal copy-depencies of maven-dependency-plugin and make the POM work as expected, copying dependencies to folder every time Eclipse build it. If you just want to ignore the error, then you change <execute /> for <ignore />. No need for enclosing your maven-dependency-plugin into pluginManagement, as suggested before.
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>

</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>
If copy-dependencies, unpack, pack, etc., are important for your project you shouldn't ignore it. You have to enclose your <plugins> in <pluginManagement> tested with Eclipse Indigo SR1, maven 2.2.1
To make it work, instead of ignoring it, you can install the m2e connector for the maven-dependency-plugin:
https://github.com/ianbrandt/m2e-maven-dependency-plugin
Here is how you would do it in Eclipse:
go to Window/Preferences/Maven/Discovery/
enter Catalog URL: http://download.eclipse.org/technology/m2e/discovery/directory-1.4.xml
click Open Catalog
choose the m2e-maven-dependency-plugin
enjoy
Despite answer from CaioToOn above, I still had problems getting this to work initially.
After multiple attempts, finally got it working.
Am pasting my final version here - hoping it will benefit somebody else.

I had the same problem when trying to load Hadoop project in eclipse. I tried the solutions above, and I believe it might have worked in Eclipse Kepler... not even sure anymore (tried too many things).
With all the problems I was having, I decided to move on to Eclipse Luna, and the solutions above did not work for me.
There was another post that recommended changing the ... tag to package. I started doing that, and it would "clear" the errors... However, I start to think that the changes would bite me later - I am not an expert on Maven.
Fortunately, I found out how to remove all the errors. Go to Window->Preferences->Maven-> Error/Warnings and change "Plugin execution not covered by lifecycle..." option to "Ignore". Hope it helps.
I know this is old post but I struggled today with this problem also and I used template from this page: http://maven.apache.org/plugins/maven-dependency-plugin/usage.html

I also got m2e error.
Another option is to navigate to problems tab, right click on error, click apply quick fix. The should generate the ignore xml code and apply it .pom file for you.
