### New and noteworthy
|
|
|
|
### CPD Suppression for Antlr-based languages
|
|
|
|
[ITBA](https://www.itba.edu.ar/) students [Matías Fraga](https://github.com/matifraga),
|
|
[Tomi De Lucca](https://github.com/tomidelucca) and [Lucas Soncini](https://github.com/lsoncini)
|
|
keep working on bringing full Antlr support to PMD. For this release, they have implemented
|
|
token filtering in an equivalent way as we did for JavaCC languages, adding support for CPD
|
|
suppressions through `CPD-OFF` and `CPD-ON` comments for all Antlr-based languages.
|
|
|
|
This means, you can now ignore arbitrary blocks of code on:
|
|
* Go
|
|
* Kotlin
|
|
* Swift
|
|
|
|
Simply start the suppression with any comment (single or multiline) containing `CPD-OFF`,
|
|
and resume again with a comment containing `CPD-ON`.
|
|
|
|
More information is available in [the user documentation](pmd_userdocs_cpd.html#suppression).
|
|
|
|
#### New Rules
|
|
|
|
* The new Java rule {% rule "java/bestpractices/UseTryWithResources" %) (`java-bestpractices`) searches
|
|
for try-blocks, that could be changed to a try-with-resources statement. This statement ensures that
|
|
each resource is closed at the end of the statement and is available since Java 7.
|
|
|
|
#### Modified Rules
|
|
|
|
* The Apex rule {% rule "apex/codestyle/MethodNamingConventions" %} (apex-codestyle) has a new
|
|
property `skipTestMethodUnderscores`, which is by default disabled. The new property allows for ignoring
|
|
all test methods, either using the `testMethod` modifier or simply annotating them `@isTest`.
|
