Prevent to update project key due to unexpected characters

[mschmieder (Matthias Schmieder)]

Peter, please see the discussion here:

Colon cannot be used in projectKey

According to official documentation colon can be used in sonar.projectKey, by default for maven project <groupId>:<artifactId> is used as sonar.projectKey. However colon is not accepted when defining projectKey in Administration → Update Key: [image] Is there any way I can use colon? I have many projects already configured to use groupId:artifactId as projectKey and want to keep this convention.

This is a breaking change that has a wide range implications for projects and governance including permission templates and auxiliary tooling! We are managing several hundred projects within SonarCloud and were hit by this change without any notice or potential workaround.
