Build class does not invoke get invoked

[Nikhil Bhoski]

Hi ,

I have created new project type . which invokes the appropriate build class to run the build . however i am receiving below error and the build wont get invoked . could someone pls help ?.

java.lang.Error: java.lang.NoSuchMethodException: matlabjenkins.matlabjnk.MatlabItemBuild.<init>(matlabjenkins.matlabjnk.MatlabItem)

I am using super.run in build class of mine and all the constructors in Build<?,?> classes are defined in my build file . <init> method may be due to no default constructor in build class . how can i resolve this and get this build invoked .

You will unlikely get help here without sharing a link to your code.
My guess is that you use the default BuildMixIn type without providing a constructor required for it

Thanks Oleg , could not share my code due to organizational policies however . My moto is to create one top level Item (new project type) which is similar to freestyle project & whenever a job is created using this project it should get invoked . i have referred to  jenkins freestyle project & freestly build class to design my own project type. i have used the exact  same methods and constructors in my project & build file . my project class is like as below 

public class MatlabItemp extends Project<MatlabItemp, MatlabItemBuild> implements TopLevelItem {

public MatlabItemp(ItemGroup parent, String name) {

super(parent, name);

}

@Override

public TopLevelItemDescriptor getDescriptor() {

return (TopLevelItemDescriptor)Jenkins.getInstance().getDescriptorOrDie(getClass());

}

@Override

protected Class<MatlabItemBuild> getBuildClass() {

return MatlabItemBuild.class;

}

/----------------------------------------------------------------------------------End------------------------------------------------------------------------------------------------------------------------------/

and my build class is like below 

public class MatlabItemBuild extends Build<MatlabItemp, MatlabItemBuild> {

protected MatlabItemBuild(MatlabItemp project) throws IOException {

super(project);

}

public MatlabItemBuild(MatlabItemp job, Calendar timestamp) {

super(job, timestamp);

}

public MatlabItemBuild(MatlabItemp project, File buildDir) throws IOException {

super(project, buildDir);

}

@Override

public void run() {

super.run();

/-------------------------------------------------------------------------------------------------------------------------------------------End ------------------------------------------------------------------------------------------------------------------------

I think you should still prefer trying to extract the gist of your code and create a PR or something reviewable online to maximize your chances to get feedback, ideally on GitHub where it's easy to do. Reviewing code in emails is a quite a bit cumbersome.

After a quick glance at the code, aren't you missing the @Extension annotation?
