After updating IntelliJ from version 12 to 13, the following Maven-related plugins cannot be resolved:
org.apache.maven.plugins:maven-clean-plugin:2.4.1
org.a
I am using IntelliJ Ultimate 2018.2.6 and found out, that the feature Reimport All Maven Project does not use the JDK, which is set in the Settings: Build, Execution, Deployment | Build Tools | Maven | Runner.
Instead it uses it's own JRE in IntelliJ_HOME/jre64/
by default. You can configure the JDK for the Importer in Build, Execution, Deployment | Build Tools | Maven | Importing.
In my specific problem, an SSL certificate was missing in the JREs keystore. Unfortunately IDEA only logs this issue in it's own logfile. A little red box to inform about the RuntimeException had been really nice...
