java - mvn install 在 eclipse 中不起作用，但在命令行中工作正常

Question

我无法通过 eclipse 构建项目，但当我运行 mvn clean install 时它工作正常。我遇到以下问题。

Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-install) on project abc-xxx: Execution default-

确保您在命令行中使用的JDK与您在IDE中使用的相同。

在命令行中输入:

java -version

然后在 eclipse 中:

 windows -> preferences -> Installed JREs

对于ma​​ven也是如此:

在命令行中输入:

mvn -version

在 eclipse 中:

 windows -> preferences -> Maven -> User settings
 windows -> preferences -> Maven -> Installations
