Troubles with SonarQube 4.3.1 and JIRA Plugin (JIRA 6.0.7)

Facing errors when linking SonarQube 4.3.1 with JIRA 6.0.7. The navigation link produces a nil error. Example code:

def process(u); u ? u : raise("missing"); end

I encountered a similar issue while attempting to integrate SonarQube with a JIRA system. After much time spent debugging, it appeared that the problem was not exclusively with the process code itself, but rather with the environment configuration between the two systems. It turned out that the newer JIRA version required additional validation steps within SonarQube’s plugin setup. I ultimately resolved the problem by making sure that all relevant settings matched the documentation instructions, and by verifying that the proper permissions were allocated to the SonarQube user in JIRA. This experience taught me the need to carefully align software versions and configurations.
