Gradle's install task from Maven plugin does not participate in incremental build

This is the -i output when running gradle install

:install Task ‘:install’ has not declared any outputs, assuming that it is out-of-date. Publishing configuration: configuration ‘:archives’ Publishing to repository org.gradle.api.publication.maven.internal.ant.BaseMavenInstaller@1f7e97a5

Hence, it is never uptodate. Seems wrong to me.
