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

Question

我無法通過 eclipse 構建項目，但是當我運行 mvn clean install 時它工作正常。 我遇到以下問題。

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

確保您在命令行中使用的JDK與您在IDE中使用的相同。

在命令行輸入：

java -version

然后在日食里面：

 windows -> preferences -> Installed JREs

---

Maven 也是如此：

在命令行輸入：

mvn -version

在日食中：

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