I don´t know what´s the problem. Trying to install maven for a college project. I already installed maven as instructed here. Picture Environmental Variables, maven version in cmd And I also tried to delete the .m2 file. When I try to install maven over the plugin in InteliJ, I get the message: "process terminated" with no extra info. Then I tried to install over the terminal with mvn clean install and i got this.

I honestly have no clue what it is telling me. Is it because there is something wrong with my pom.xml? Pls help me! Thank you in advance.

Edit: I used the spring boot intitializer to create the project.
The MojoExecutionException should not appear after that. Some Eclipse versions have this problem to refresh the target folder. In this case, Refresh the project just after the "Maven Install".
The Maven Clean Plugin, as the name implies, attempts to clean the files and directories generated by Maven during its build. While there are plugins that generate additional files, the Clean Plugin assumes that these files are generated inside the target directory.
The Resources Plugin handles the copying of project resources to the output directory. There are two different kinds of resources: main resources and test resources.
To view full stack traces, please go to the Settings->Maven and check the 'Print Exception Stack Traces' box.
It might be a new bug coming with some latest release of Spring-boot (and then : Spring).
I had it. The workaround is to put in your pom.xml
this corrected dependency :
