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

Question

I am unable to build a project through eclipse but it works fine when I run mvn clean install. I am getting the following issue.

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

Make sure the JDK you are using in the command line is the same that you are using in your IDE .

In the command line type:

java -version

Then inside eclipse:

 windows -> preferences -> Installed JREs

---

The same goes for maven :

In the command line type:

mvn -version

In eclipse:

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