Description

We have a class methods that's like this:
/**

  • Takes an Iterable of Iterables of T and flattens it down to a Collection
  • of T.
    */
    public static <T, Source extends Iterable<? extends Iterable<T>>, Store extends Collection<T>> Store flatten( Source source, Store store ) {
    for ( Iterable<T> subSource : source )
    Unknown macro: { for ( T t }

    return store;
    }

We are running hudson+sonar plugin, when we reach the sonar build we get this error:

[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Cannot execute the command org.codehaus.mojo:javancss-maven-plugin::report

Embedded error: An error has occurred in JavaNCSS Report report generation.

Was expecting one of:

Sorry, I can't give you a link, it's not an open source project. You should be able to reproduce it using the full method body:

/**

  • Takes an Iterable of Iterables (e.g. a list of lists), of T and flattens
  • it down to a Collection of T.
    */
    public static <T, Source extends Iterable<? extends Iterable<T>>, Store extends Collection<T>> Store flatten(Source source, Store store) {
    for (Iterable<T> subSource : source)
    Unknown macro: { for (T t }

    return store;

You will have some compilation errors, but if you create some fake interfaces for Store, Source and Iterable it should then work.

Thanks.

Sorry I've just realized that JIRA tries to parse the java code and to create a macro.

With the code attached you should be able to reproduce the problem .

Thanks.
