m2eclipse

问题 I have just downloaded and installed M2Eclipse, but it fails to update the index of the central repo. At the same time, Maven itself is able to download artifacts from the repo (via command line). I had the settings.xml file in maven/conf , and I copied it to .m2/ directory, but it didn't help. I have proxy, but proxy settings are given in settings.xml - commands from command line work fine, but not in Eclipse. In Eclipse it gives me this: Unable to update index for central|http://repo1.maven

问题 do I understand correctly, that Java builder recompiles sources on scr path to the output path, which usually happens after each "ctrl + s" if automatic building is activated or via "ctrl + b" or throws validation errors from javac.

问题 I want to add jpoller.jar as a maven dependency, so I edited my pom.xml file to include it: <dependency> <groupId>org.sadun</groupId> <artifactId>jpoller</artifactId> <version>1.5.2</version> </dependency> Now, as expected, when I compile from the command line I get an error because jpoller isn't in any of the repositories I have listed in my pom, nor could I find one for it. Although I could create a repository for it, I'd rather not at this point. Thus, I get the following error: [INFO]

问题 I'm sorry if I am asking a possibly-trivial question, but I am having so much trouble finding out exactly what Resolve Workspace Artifacts does in the Maven build window in the Eclipse IDE, using the M2Eclipse plugin. I'm referring to this: Does anyone have any idea? I tried google-ing and stackoverflow-ing the solution; there are lots of bug requests/reports but no clear-cut descriptions of this option. Thanks for the help. 回答1: Assume you have two or more projects in your workspace e.g.

问题 I am trying to use the maven-warpath-plugin available here.

问题 I am starting to configure my development environment and I am using Spring Tool Suite 2.8.1 along with m2E 1.01. As far as I can tell, since this is a Maven Project (my first), my Maven POM is dictating (along with m2E smarts) my project build configuration and dependencies. What I would like to know is why my IDE is displaying Java Build Problems that read "Archive required for library library/path/somejar.jar cannot be read or is not a valid zip file" when I can see the jars in my .m2
