4. Fix it.

Found a solution. Add the javax annotation dependency into build.gradle

    dependencies {
        compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25'
        ...
        implementation 'javax.annotation:javax.annotation-api:1.3.2' 
     }

Try build.

./gradlew clean build -x test
