I'm working with several projects and some of them doesn't compile with this error message that belongs to the pom.xml file:
In the overview tab of the pom.xml editor, I can click the error in order to tell STS to search for an appropriate connector. It works but it finds nothing.Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available. To enable full functionality, install the lifecycle mapping and run Maven->Update Project Configuration.
The weird thing is:
* Some projects compiles one day, but the next day shows the error. If I delete the project, re-import it or even close the entire STS it compiles again.
For instance, the Spring Integration samples that are available at github: /basic/file or /basic/helloworld
* Other projects doesn't compile ever, but when I using maven from the console I see a BUILD SUCCESS.
Does anybody else have the same problem?
