* Use the "core-modules" profile if working on the Pulsar core modules since the source code for those modules can be compiled in IntelliJ.
* Sometimes it might help to mark a specific project ignored in IntelliJ Maven UI by right-clicking the project name and select **Ignore Projects** from the menu.
* Currently, it is not always possible to run unit tests directly from the IDE because of the compilation issues. As a workaround, individual test classes can be run by using the `mvn test -Dtest=TestClassName` command.
+
+* The above steps have all been performed, but a test still won't run.
+ * In this case, try the following steps:
+ 1. Close IntelliJ.
+ 2. Run `mvn clean install -DskipTests` on the command line.
+ 3. Reopen IntelliJ.
+ * If that still doesn't work:
+ 1. Verify Maven is using a supported version. Currently, the supported version of Maven is specified in the
+ <requireMavenVersion> section of the main pom.xml file.
+ 2. Try "restart and clear caches" in IntelliJ and repeat the above steps to reload projects and generate sources.
