How do I get a Java maven build to fail for compiler warnings?

Question

I am trying:

        
            org.apache.maven.plugins
            maven-compiler-plugin&l         


        

Answer 1

New in maven-compiler-plugin 3.6.0: the failOnWarning flag. This worked for me:

  
    maven-compiler-plugin
    3.6.0
    
      
        compile
        process-sources
        
          compile
        
        
          -Xlint:-processing
          true
        
      
    
  

Note that I had to exclude the processing lint or otherwise auto-matter's annotations would break the build with cryptic "symbol not found" errors.
