Can you please check your console or the Jenkins log too see if there is an exception thrown?

I have checked. Nothing seems related.

Which browser are you using? Are there any problems reported when using a JavaScript Debugger like Firebug?

I used Chrome and IE, both of them have problems. I have upload all my installed plugin capture, can you find something conflict with Warning-plugin?

Actually I don't see why there is a problem on your system. One thing that we could check, in order to investigate this bug:

1. On the same system, start Jenkins in a new JENKINS_HOME directory with java -jar jenkins.war
2. Install the warnings plug-in using the update manager
3. Restart Jenkins and try the add buttons

Dependening on the results we can decide which steps should be next...

I start a new Jenkins with different Jenkins_home and different port, warnings-plugins still can not be work. So I guess something related to my enviroment impact its work. Any clue?
Oh, by the way, I still use Jenkins 1.475.

Is 1.475 a LTS release? Maybe download a newer version and retry...

I have to report the same issue. Jenkins version is 1.480.3, Plugin Version is 4.23.

[Steps to reproduce]

• Add post build step "Scan for compiler warnings"

[Expected behavior]

• Jenkins adds post build step

[Additional info]

• If it helps: I was able to add the "Task Scanner" Plugin as a post build step successfully.

[Actual behavior]

• Nothing happens

The follow

@Eric I'm not sure if this is the same problem: in your case you can't add the post build action. yufei could add the post build action, but could not select warning parsers...

But anyway, good to see that in your case an exception is thrown. Can you please try to install the violations plug-in and restart? Or is it already installed?

@Ulli Hafner
I start a new JENKINS in a different PC(WIN XP 32bits),and download warnings plugin, it still not work. I click add button, still nothing happened. But the 'Advanced' button works well. I guess some lib or dll used in this plugin need to install, but I can not figure out what is it as nothing appears in console.

@Ulli: Thanks for the quick reply. Violations is already installed (Version 0.7.7). The violations plug in had been installed before the Warnings plug in. We recently upgraded from Hudson V1.395, the Violations plug in was installed before the upgrade, the warnings plug in was installed after the upgrade.

Sorry for interrupting this topic with another issue. Should I open a new ticket?

@Eric: Yes please either try to upgrade the violations plug-in or remove it if not necessary. Maybe your version conflicts with the version my plug-in requires (the dependency is optional: the warnings plug-in reuses the parsers of the violations plug-in if installed). If that does not help, please file a new bug report...

Following is console ouput from I start Jenkins to I click add button. No ouput for hitting button...

Which Java version are you using?
YF: Both machines use 1.7

@Ulli: Thanks - updating the violations plug in has resolved my issue.

@Ulli Hafner
Hi, I still cann't get console log parser, but I modified job's config.xml and add WarningsPublisher, then restart Jenkins, now I can add log parser for this job now.. Do you think plugin can work?
Another question, do we have any out put for the result, like some xml file? Thanks.

I can get files such as "JavaCompilerjavac-warnings.xml" under builds folder, but I cann't find such file under project folder.

Is this still a problem, I can't reproduce this bug.
