For the specific case of the JVM heap size, as of Java 8 update 131, the JVM knows how to see Docker memory limits. As of Java 8 update 190, the default maximum heap size is 25% of available memory, but you can change this, for example

Spring's complaint is that you haven't defined a Bean of type ProjectMapper, which it is saying that it needs to satisfy an Autowire request. Looking at your code, I don't see a definition for such a Bean in what you've shown us here.

There is no such single action. But it is possible to find the corresponding for the library pom with these steps:

1. F4 (Go to source action) on selected item in External library will open this library configuration dialog:

1. Then use Alt+F7 (Find usages action) to show the module where this library is used:

1. Then you can find this module in Maven tool window (use speed search for example to locate it more easily), select it in the tree and navigate to corresponding pom using F4 (Go to source action) again:
