问题 I'm trying to use eclipse jdt , and I tried to import related modules in java source file. I have a bunch of errors as the jdt libraries are not in Java Build Path. I tried to open Add Libary -> Plug-in Dependencies , but it doesn't have the jdt jar files. I could use Add External JARs to point to all the jar files, but I don't think it's a good idea considering I have to do the same thing over and over again with new projects. In this case, how to put eclipse jdt jar libraries in Java Build

I have also seen this question on SO: "Intellij IDEA using java7 compiler to compile when I have configured it to use Java6", but

问题 I'm new to Maven and m2e. It frustrates me that I have to ask this question, but the sparse m2e documentation and Google are failing me. How do get m2e to build a JAR? I understand that this should happen during the maven package phase, but m2e doesn't seem to do this as part of the build process and I can't find a way to explicitly execute the package phase in Eclipse (nor any other phases that aren't part of the default build). Thanks. 回答1: As long as you have your POM.xml file with the

问题 How can I include all the jar files under lib in my main jar file produced ? Is IntelliJ meant to create JAR files or not ? Cause I can't seem to make it work.
