Tasks with public fields can't be annotated with @InputFile/@OutputFile/

(David Pärsson) #1

Assigning input/output file annotations to public fields will not make the fields be inputs/outputs, when there are no getters defined, as below.

class MyTask extends DefaultTask {
    public File outputFile
    public FileCollection inputFiles
    def doSomething() {
        // ...

It would be very helpful if Gradle at least could fail the build when/if this is detected.

Removing the “public” keyword from the field declaration will make everything work as expected.

I think the problem is that Gradle initially looks for getters rather than fields. A Groovy property declaration (‘File outputFile’) generates a getter, whereas a field declaration (‘public File outputFile’) doesn’t. As it can be difficult to make sense of this, I’ve raised GRADLE-3043.

Thank you!
