Converting a Mono-language Project to a Multi-language Project
The first step is to choose which one of these two mono-language projects you will convert to a multi-language project. You will lose the history (timeline, false positives, action plans, etc.) on the one that won't get converted to a multi-language project. In this example, we'll choose to convert the Java project to a multi-language project as most of our code (and therefore history) is Java.
The second step is to run another analysis of this Java project the old way (make sure to explicitly set the
sonar.language property to
java). This step is mandatory to keep the history on the project.
The third and last step is to remove the
sonar.language property and set the
