How to suppress specific Kotlinc/Javac compiler warnings?

问题

How to suppress deprecations in for KotlinCompile in Gradle similar to JavaCompile?

JavaCompile(works):

tasks.withType(JavaCompile) {
    configure(options) {
        compilerArgs << '-Xlint:-deprecation'
    }
}

KotlinCompile(does not work):

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile) {
    kotlinOptions {
        freeCompilerArgs = ["-Xjavac-arguments=-Xlint:-deprecation"]
    }
}

回答1:

It looks like there is a suppressWarnings option on the kotlinOptions property defined on the KotlinCompile task. Setting that to true may do what you want.

This is how you would do that:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile) {
    kotlinOptions {
        suppressWarnings = true
    }
}
