Dale King commented on MNGECLIPSE-89: ------------------------------------- I understand why the problem happens. But I think there is still the issue that this is very likely to occur with other users and there is nothing in build errors to tell you why you are unable to build. I think the Maven Eclipse plug-in should do a check when it starts a build to check to see if the user has inadvertantly set up their JRE to point to a JRE instead of a JDK and give them an alert telling them that they will not be able to build Java unless they correct this. > Compile goal fails with exception > --------------------------------- > > Key: MNGECLIPSE-89 > URL: http://jira.codehaus.org/browse/MNGECLIPSE-89 > Project: Maven 2.x Extension for Eclipse > Type: Bug > Components: Maven Launcher > Versions: 0.0.5 > Environment: Windows XP, Eclipse 3.1.2 > Reporter: Dale King > Assignee: Eugene Kuleshov > > > Used archetype to generate project as specified in Maven documentation and > use that generated folder as Eclipse project.
