Antony Stubbs commented on MCOBERTURA-42:
-----------------------------------------
If it helps in re-producing it - the src/main only contains a sub directory and
a .properties file inside. Perhaps it's checking for the src/main/java dir,
instead of checking for actual .java files?
> [cobertura] plugin should handle projects with no source code
> -------------------------------------------------------------
>
> Key: MCOBERTURA-42
> URL: http://jira.codehaus.org/browse/MCOBERTURA-42
> Project: Maven 2.x Cobertura Plugin
> Issue Type: Bug
> Environment: Maven 2.0.4
> cobertura-maven-plugin 2.0
> Reporter: Jimisola Laursen
>
> The Cobertura Maven Plugin fails when it can't find a cobertura.ser file
> (see end).
> However, not all Maven projects have source code. E.g. a top level pom (i.e.
> packaging = pom) doesn't.
> We have all our sub projects use cobertura and we therefore have cobertura
> configured in the top level pom which eases everything a lot.
> The plugin should simple ignore to run when the current project has pom
> packaging.
> I've mentioned to the Maven Team that this is a general problem with many
> plugins and that it therefore should be a general solution for this,
> but so far they feel that it is up to each individual plugin since e.g.
> surefire-plugin doesn't fail if there are no test classes.
> Anyway, it a small fix:
> 1) add new property executeOnPackaging
> /**
> * Configures for packaging types this plugin should be executed
> * @parameter property="executeOnPackaging"
> * @require
> */
> private String executeOnPackaging[] = new String[] {"jar", "war", "ear"};
> 2) add check to execute method
> public void execute() throws MojoExecutionException, MojoFailureException
> {
> // IMPORTANT: must sort - otherwise binarySearch won't work
> Arrays.sort(this.executeOnPackaging);
>
> if (Arrays.binarySearch(this.executeOnPackaging,
> this.project.getPackaging()) < 0)
> {
> this.getLog().info("Cobertura plugin not run since project
> packaging " + this.project.getPackaging() + " is not one of " +
> this.executeOnPackaging);
>
> return;
> }
