升级IntelliJ IDEA 2019.3(CE)后Maven插件无法解析的求助

I recently upgraded IntelliJ from 2019.2.x to 2019.3, and also updated Maven from 3.6.0 to 3.6.3 (using Java 11). After these upgrades, my Java project started throwing Maven plugin resolution errors:

• Failed to resolve plugin org.codehaus.mojo:exec-maven-plugin:1.6.0
• Failed to resolve plugin org.apache.maven.plugins:maven-resources-plugin:3.1.0

Solution #

After digging into the issue, I found out this had nothing to do with the IntelliJ or Maven upgrades! Here's what went wrong and how I fixed it:

1. Root Cause: I was working from home and forgot to connect to my company's VPN. Our project is configured to pull dependencies from an internal Nexus repository, which isn't accessible without the VPN. When I first tried to build after upgrading, Maven failed to reach the Nexus repo and cached that failure. Even after connecting the VPN later, Maven wouldn't retry the download automatically because of the cached failure.

2. Fix Steps:

   • First, connect to your company VPN (if you're using an internal repository)
   • Force Maven to update dependencies and clear the cached failure by running this command in your project root:

     mvn clean install -U
     

   • Alternatively, you can manually delete the cached plugin folders from your local Maven repo (usually located at ~/.m2/repository/org/codehaus/mojo/exec-maven-plugin and ~/.m2/repository/org/apache/maven/plugins/maven-resources-plugin) then re-run your build.

Once I did this, Maven was able to successfully resolve the plugins and the project built without issues.
