error: cannot find symbol @Generated( ^

Building via Android Studio works fine, but if I call

./gradlew build

I get

error: cannot find symbol
@Generated(
 ^

all over the place. I’m using the latest version of dagger. My android project is set to Java 8 source. Calling java --version in my terminal tells me I have java 9 (which I’m not sure how, but I that’s besides the point). Any ideas what I should be doing? I’ve seen a bunch of mixed answers on stackoverflow, but adding a dependency feels weird. My system being on java 9 doesn’t make sense to me because I though Android Studio bundles it’s own version of the JDK.

I managed to work around this on a JDK 11 install by adding the following to the bottom of my affected modules’ build.gradle files. I imagine it would work in a subprojects.afterEvaluate block in the top-level build.gradle too.

    if (project.hasProperty('kapt')) {
        // Reference for 'kapt' DSL: https://kotlinlang.org/docs/reference/kapt.html#java-compiler-options
        kapt {
            // we expect this closure to run over a org.jetbrains.kotlin.gradle.plugin.KaptExtension
            javacOptions {
                option("-source", "8")
                option("-target", "8")
            }
        }
    }

In Kotlin 1.3.70 it’s fixed
