This is the new behaviour of m2e (which replaced the old m2eclipse plugin). To specify what eclipse should do with the plugin you have to configure the build lifecycle mapping in the project’s pom.xml – or install a connector (which decides if the plugin needs to be executed in an eclipse build or not) if … Read more
Assume you have two or more projects in your workspace e.g. project1, project2 and so on. If project1 is dependent on project2 and project3, you just need to define the dependency of project1 on project2 and project3. By enabling Resolve Workspace Artifacts, m2Eclipse will auto-build the SNAPSHOT JAR of project2 and project3 and add in … Read more
My team works around this problem by wrapping the relevant configuration in a profile: <profile> <id>only-eclipse</id> <activation> <property> <name>m2e.version</name> </property> </activation> <build> <pluginManagement> <plugins> <plugin> <groupId>org.eclipse.m2e</groupId> <artifactId>lifecycle-mapping</artifactId> <version>1.0.0</version> <configuration> … </configuration> </plugin> </plugins> </pluginManagement> </build> </profile>
Indeed IDEs often cache the local repository (Eclipse does something similar, and I have to relaunch Eclipse). One ugly maven behavior you might encounter is that if you declare a dependency before you actually install it, maven will create an empty version of the missing dependency (folder with metadata but no jar), and you will … Read more
I ran into a similar issue today and found that this question also has recently been asked and answered at the atlassian forum as well. My solution was to install slf4j based on guidelines from this blog post about “SLF4J Logging in Eclipse Plugins”. To extract, here is what I did: Eclipse -> Help -> … Read more
The org.eclipse.m2e:lifecycle-mapping plugin doesn’t exist actually. It should be used from the <build><pluginManagement> section of your pom.xml. That way, it’s not resolved by Maven but can be read by m2e. But a more practical solution to your problem would be to install the m2e build-helper connector in eclipse. You can install it from the Window … Read more
