Generate diagrams under build directory instead

[TAGC]

I think it would be better to generate UML files under a subfolder of the build/ directory rather than under src/main/java, considering these are generated artifacts and not source files.

I've added this code to my Gradle build script and it seems to be working:

/**
* Moves UML files generated by :plantuml to subdirectories of the build/ folder.
*/
project.tasks.plantuml.doLast {
    def sourceBase = file(plantuml.sourcePath).absolutePath + File.separator
    def buildBase = file("$buildDir/docs/uml").absolutePath + File.separator
    def umlFileExtension = "$plantuml.fileFormat".toLowerCase()

    /*
    * Iterate for each file operated on by :plantuml.
    */
    plantuml.sources.each { File sourceFile ->      
        def sourceFileBase = sourceFile.name.split("\\.")[0]
        def fileDir = sourceFile.getParentFile()

        /*
        * Iterate for each file in the parent directory and move discovered UML files
        * under build/.
        */
        fileDir.eachFile (groovy.io.FileType.FILES) { File possibleUmlFile ->
            if (possibleUmlFile.name.startsWith(sourceFileBase) && possibleUmlFile.name.endsWith(umlFileExtension)) {
                def newUmlPath = file(buildBase + (possibleUmlFile.absolutePath - sourceBase))

                newUmlPath.getParentFile().mkdirs()
                possibleUmlFile.renameTo(newUmlPath)
            }
        }
    }
}

👍 For the feature request.

But your implementation assumes that every source file is under sourceBase, by default src/main/java. Furthermore, it also assumes that all files under sourceBase ending in png were generated by plantuml. I'd rather had something more in the gradle spirit (supporting source sets, in contrast to one specific dir)^*.

By the way, how does it cope with javadoc generation? Are these pngs included in the generated javadoc?

^* I have spent a few hours trying to implement this myself, but it's proving to require better gradle skills than those that I have at the moment.
