Gradle 5.0 causes error Val cannot be reassigned when using Kotlin DSL in buid.gradle.kts #1265

Closed clementohNZ closed 5 years ago

clementohNZ commented 5 years ago

Expected Behavior

I expect the build to complete successfully because when I use gradle 4.10.2 on the same build.gradle.kts file the error Val cannot be reassigned doesn't appear.

Looking into the class JacocoReportBase I can see that the class property classDirectories is not final and a valid setter has been provided.

public abstract class JacocoReportBase extends JacocoBase {
    private FileCollection executionData;
    private FileCollection sourceDirectories;
    private FileCollection classDirectories;

    ...

    public void setClassDirectories(FileCollection classDirectories) {
        this.classDirectories = classDirectories;
    }

Current Behavior

Gradle spits out a Val cannot be reassigned error.

Context

I can no longer build my pipeline and would have to look into downgrading back to version 4.10.2

Steps to Reproduce (for bugs)

Try to set the classDirectories property in build.gradle.kts using Kotlin DSL.

Can you provide the full stack trace?

davidmoshal commented 5 years ago

same thing has been happening with me after 5.0-rc-1 ie: a build file works fine with: 4.1 4.2 4.10 5.0-rc-1

but, results in this error with 5.0rc-2 5.0-rc-3, and 5.0 (ie: the release version):

* What went wrong:
Script compilation errors:

  Line 307:     classDirectories = files("build/classes")
                ^ Val cannot be reassigned

  Line 308:     sourceDirectories = files("src/main")
                ^ Val cannot be reassigned

2 errors

if I rollback to 5.0-rc-1 the error goes away !

and here are the relevant lines in the build file, lines 307 and 308 are marked below:

tasks.withType<JacocoReport> {
    dependsOn("test")
    reports {
        html.apply {
            isEnabled = true
            //destination = File("reports/jacoco.xml") // defaults to: File("build/reports/jacoco.xml")
        }
        executionData(tasks.withType<Test>())
    }
    classDirectories = files("build/classes")    # line 307
    sourceDirectories = files("src/main")        # line 308
}

NOTE: commenting out the JacocoReport task resolved the problem. (I'm not currently using that task anyway).

clementohNZ commented 5 years ago

Apologies for the late reply @JLLeitschuh haven't been free since haha. I have included the stack trace above :)

jivimberg commented 5 years ago

Running into this too. How do you guys get the Kotlin compiler stacktrace?

clementohNZ commented 5 years ago

@jivimberg you can add the --stacktrace option to your gradle command e.g. gradle dependencies --stacktrace :)

I'm also seeing Val cannot be reassigned on Gradle 5.0 with JaCoCo.

Looks like classDirectories actually is not a writible property anymore: if you look at the source getClassDirectories has return type of ConfigurableFileCollection and setClassDirectories accepts FileCollection. So this is not a valid Java Beans property, because getter and setter operate on different types. So only getter is seen by Kotlin as val and assignments are not supported. It's a feature.

You can either try to call setClassDirectories directly (setClassDirectories(…) instead of classDirectories = …), or to use classDirectories.setFrom, as suggested by the Javadocs.

bootstraponline commented 5 years ago

Thank you! classDirectories.setFrom solved the issue.

clementohNZ commented 5 years ago

@madhead @bootstraponline just wondering where the setFrom method comes from because I can't seem to find it.

I'm currently using the manual calling of the setter like so:

@Suppress("UsePropertyAccessSyntax")
setClassDirectories(files(filesToCover))

Cheers :)

madhead commented 5 years ago

It's here.

clementohNZ commented 5 years ago

Just wondering if there's a version difference for us because when I look at the getter it returns a FileCollection not a ConfigurableFileCollection so the setFrom method is not available to me.

@PathSensitive(PathSensitivity.RELATIVE)
@InputFiles
public FileCollection getClassDirectories() {
    return classDirectories;
}

Cheers :)

madhead commented 5 years ago

@clementohNZ, take a look at this commit: https://github.com/gradle/gradle/commit/76fecd4f823a1108f0044a2269aad92383a6660e.

clementohNZ commented 5 years ago

awesome! I'll get the right version and report back :) thanks @madhead

davidmoshal commented 5 years ago

Might explain why Gradle version > 5.0-rc-1 failed with this error?

clementohNZ commented 5 years ago

cool ~ this is working for me now classDirectories.setFrom(files(filesToCover)). Not really sure why it's working for me now though because I haven't changed from gradle tag v.5.0.0 😮 perhaps it was a local caching issue? either way I'll close this for now and upvote your stackoverflow answer 😄 Thank you @madhead !
