Candlepin uses Checkstyle to ensure the code remains as readable as possible. You can run checkstyle from both the command line and from within Eclipse.
Run the following command: ./gradlew checkstyleMain checkstyleTest and the results will be
printed out to your console.
On occasion you will need to override Checkstyle. For example, if you use a JUnit Rule, JUnit requires that the Rule object be public which violates our Checkstyle requirement that fields be private and use accessors.
To get around this false positive, you can tag your code with the
@SuppressWarnings annotation and provide the violated module as the
argument. For example:
@SuppressWarnings("checkstyle:visibilitymodifier")
@Rule
public ExpectedException ex = ExpectedException.none();
Of course, this requires that you know the name of the Checkstyle module that
the code is failing. I do not currently have a fool-proof way of determining
the module. Usually I look in the project_conf/checks.xml file and do a
little trial and error.
