Solution

If you use multiple Maven modules in your project, this may apply to you: I mainly use Maven through the console, so I don't have any experience under the solar eclipse, but Maven supports parallel construction since Maven 3 This feature is out of the box, but its success depends on the plug-in you use, because third-party plug-ins may not be designed to work like this

To activate parallel builds, start Maven with the - t parameter:

mvn clean install -T 2

Build with 2 threads

mvn clean install -T 2C

Each CPU builds two threads

Maven will determine the build order and parallelize it as much as possible

Sadly, if your project module structure is very linear, i.e. project a – > project B – > project C, this will not be beneficial
