checkstyle/checkstyle

Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.

Hi everyone, I would like to know if there is a check in Checkstyle which verifies the correctness of placeholders in String.formator any similar formatting method?

Here are 3 examples:

jshell> String.format("Hello, %s", "Checkstyle");
$1 ==> "Hello, Checkstyle"

jshell> String.format("Hello, %s", "check", "style");
$1 ==> "Hello, check"

jshell> String.format("Hello, %s");

Hello All,
Newbie here, so please go easy on me. I have some binary source files which I do not want to fingerprint. Obviously UTF-8 encoding is not correct. I was wondering if there was a way to avoid such error messages.

[CheckStyle] [-ERROR-] Can't create fingerprints for some files:
[CheckStyle] [-ERROR-] - 'C:/Jenkins/workspace/example_master/Add.vi', provided encoding 'UTF-8' seems to be wrong

My analysis step in my pipeline looks like this:

recordIssues(
enabledForFailure: true, forensicsDisabled: true, unstableTotalAll: 1, healthy: 1, unhealthy: 10,
tools: [checkStyle(pattern: 'build_temp\VIA_results.xml', reportEncoding: 'UTF-8')]

Please help.

Thanks in advance.

Unfortunately that error is not coming from main Checkstyle jar, so I don't know how to help you. You would have to look more into jenkins

sreejith-sjrs

@sreejith-sjrs

OK. Thanks very much for getting back to me. I will try to reach out Jenkins folks

Hi, Is there any easy way to add custom checkstyle rules, to fail build for using specific classes

Roman Ivanov

@romani

While checkstyle/checkstyle#6481 is not done, no very easy way, but you are welcome to contribute such implementation

@pbludov

Pitest is broken because I messed up the System.err and System.out when migrating to Junit5. Soon there will be a PR with a fix.
