CppCheck(XML parsing) with Warning-Next-Generation plugins

[Hakan Rafik]

I'm using the next generation plugins to represent the CppCheck warnings and errors.

But the plugins is not parsing Carriage return: 
 or Line feed: 
.


I've tried to feed the plugins with the given example (https://github.com/jenkinsci/warnings-ng-plugin/blob/master/plugin/src/test/resources/io/jenkins/plugins/analysis/warnings/cppcheck.xml) generates error and didn't produces any formatted string.




Any help in this regards is highly appreciated.

When you don’t show error messages or log messages we cannot help. Just writing that it does not work is not enough information.

Thanks for your reply.

I've used the example xml from the given link, and getting error -

For me that looks like an issue of your shell command and not of the plugin. Can you try to store the actual file to your workspace and make the plugin parse that?

For me the warnings.ng.plugin is just working in conjunction with cppcheck.

What I am doing looks like this:

The cppcheck-call:

cppcheck --xml --output-file="cppcheck-result.xml"  --library=D:\cppcheck.cfg --platform=win32A --template="{file},{line},{severity},{id},{message}" .

and the plugin-part:

      stage('Static Analysis') {
                    steps {
                        // call cppcheck as part of a Makefile target
                        recordIssues sourceCodeEncoding: 'ISO-8859-1', tools: [cppCheck(pattern:'**/cppcheck-result.xml')]
                    }
                }

Exactly!

The log indicates that my plugin does not even run since the build already failed. (You can change that behavior but I think it makes more sense to correct your build.) 

If you want to test the plugin I can recommend the plugin https://github.com/jenkinsci/file-operations-plugin

I’m using that in my testing courses to create manual integration tests that use fake input files for my warning plugin.

With this plugin you can create an example file for cppcheck in the workspace.

Thanks for the reply.

What I've done is, put this,

echo '<?xml version="1.0" encoding="UTF-8"?>
<results version="2">
  <cppcheck version="1.52"/>
  <errors>

  <error id="variableScope" severity="style" msg="The scope of the variable 'i' can be reduced" verbose="The scope of the variable 'i' can be reduced. Warning: It can be unsafe to fix this message. Be careful. Especially when there are inner loops. Here is an example where cppcheck will write that the scope for 'i' can be reduced:&#xa;void f(int x){&#xa;    int i = 0;&#xa;    if (x) {&#xa;">
    <location file="api.c" line="498"/>
  </error>
  </errors>
</results>'

inside execute shell command, under Build. Set Tools CPPCheck and Build.

I was waiting that the &#xa; would produce new line where used. But they didn't.

Hi,

maybe not what you are looking for, but I do run my cppcheck with the following command (bat or sh):

 

def RunCppCheck(scriptConfig, outputXml, otherOptions = "") {

String cmd = “cppcheck --project=${scriptConfig} --xml --xml-version=2 ${otherOptions} 2> ${outputXml}”;

if(isUnix()) {

  sh(cmd);

} else {

     bat(cmd);

 }

}

 

Then I parse the output xml file like any unit tests results or you can use warning parsings regex. By the way the command line doesn’t support the gui project file (the command line into cppcheck are trash big time. They clearly added command line aside of the gui and this lead to ugly command line.
