Stefan Miklosovic updated CASSANDRA-17925:
------------------------------------------
Description:
After we cleaned all unused imports in CASSANDRA-17876, there is one more task
remaining to be done - to add checkstyle for imports order and enforce this on
build time.
When the project is imported into IDEA, there is a helper target on Ant called
"generate-idea-files". ide/idea/codeStyleSettings.xml contains this:
{code:java}
<option name="IMPORT_LAYOUT_TABLE">
<value>
<package name="java" withSubpackages="true" static="false" />
<package name="javax" withSubpackages="true" static="false" />
<emptyLine />
<package name="com.google.common" withSubpackages="true"
static="false" />
<package name="org.apache.log4j" withSubpackages="true"
static="false" />
<package name="org.apache.commons" withSubpackages="true"
static="false" />
<package name="org.cliffc.high_scale_lib" withSubpackages="true"
static="false" />
<package name="org.junit" withSubpackages="true" static="false" />
<package name="org.slf4j" withSubpackages="true" static="false" />
<emptyLine />
<package name="" withSubpackages="true" static="false" />
<emptyLine />
<package name="" withSubpackages="true" static="true" />
</value>
</option>
{code}
However, when one runs "Optimise imports" in the context menu after
right-clicking on org.cassandra.apache package, it will refactor all the
imports which adheres to the above codestyle with hundreds or changes.
This means that the source code, as-is, does not adhere to the self-imposed
code style we ship for IDEA.
If we fix this, we should add checkstyle for it like this:
{code:java}
<module name="ImportOrder">
<property name="groups"
value="/(^java\.|javax)/,/(com\.google\.common|org\.apache\.log4j|org\.apache\.commons|org\.cliffc\.high_scale_lib|org\.junit|org\.slf4j)/"/>
<property name="ordered" value="true"/>
<property name="separated" value="true"/>
<property name="option" value="bottom"/>
<property name="separatedStaticGroups" value="false"/>
<property name="sortStaticImportsAlphabetically" value="true"/>
</module>
{code}
This checkstyle on import order will pass on the source code we run the import
optimisation in the context menu on.
This should be applied to test checktyle as well and the source code should be
refactored on imports too.
This should be done on cassandra-4.1 as well as for trunk.
