---------------------------------------
Summary: Checkstyle fails to compile assignment of anonymous class
with generics
Key: MCHECKSTYLE-183
URL: https://jira.codehaus.org/browse/MCHECKSTYLE-183
Project: Maven 2.x Checkstyle Plugin
Issue Type: Bug
Affects Versions: 2.9.1
Environment: Apache Maven 3.0.4 (r1232337; 2012-01-17 00:44:56-0800)
Maven home: /home/rchen/dev/tools/apache-maven-3.0.4
Java version: 1.6.0_26, vendor: Sun Microsystems Inc.
Java home: /home/rchen/dev/tools/jdk1.6.0_26/jre
Default locale: en_CA, platform encoding: UTF-8
OS name: "linux", version: "2.6.36-020636-generic", arch: "amd64", family:
"unix"
Reporter: Ronald Chen
Attachments: checkstyles-override-with-generics-fixed.tar.gz
Attached is a repo case where checkstyles fails to compile valid code and hence
fails.
To run attached code use: mvn checkstyle:check
The checkstyles parser doesn't like code like:
{code}
CheckstylesOverrideWithGenericsBug assigned = new
CheckstylesOverrideWithGenericsBug() {
@Overrdie
public <SRC> void doStuff(SRC src) {
}
};
{code}
The workaround is to remove the generics and use a more specific type. In the
attached file I've include two more other cases which don't reproduce the
problem.
Another problem is checkstyles fails when it fails to parse code. This is
horrible. Checkstyles should skip over files it cannot parse unless you can
guarantee the checkstyles parser is as good as all other java compilers.
