java - 路径必须包含项目和资源名称/错误

Question

我已经使用以下选项在 Eclipse 中 checkout 了一个 Maven 项目:

Import > Maven > Check out Maven Projects from SCM

当我尝试使用以下方式构建项目时:

Project > Clean

我收到以下错误:

Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

堆栈跟踪:

session 数据:

java.version=1.7.0_17
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.java.product
Command-line arguments:  -os linux -ws gtk -arch x86_64 -product org.eclipse.epp.package.java.product

我看不出配置有任何问题。其他人检查过这个项目，没有出现这个错误。我不知道它说“路径必须包括...”时指的是什么，在哪里可以配置此路径？

Answer 1

这是由本地定义的名为 $BROOT 的环境变量引起的，该变量在 ~/.bashrc 中设置，然后由 maven pom.xml 获取。环境变量将项目的输出目录放在 Eclipse 工作区之外，这不是 Eclipse 喜欢做的事情。

解决方案是取消设置环境变量。这就是它在 Windows 中工作的原因，因为 Windows 不知道 ~/.bashrc 的任何信息。
