Instruction step to build camunda-bpm-platform from git

Hi, could somebody point me at the most up to date instruction steps to build the following Camunda 7 Community edition tag: GitHub - camunda/camunda-bpm-platform at 7.18.0 please?
Unfortunately for me, it is failing at the mvn compile stage so potentially I am missing some further configuration.

Failing step:
[INFO] Camunda Platform - webapp - app … FAILURE [ 7.003 s]
