Description

(branch|patch)-javac-root-warning.txt is always empty though there are some warnings on ant-based projects, because check_patch_javac filters warning messages as follows:

      if [[ -f "${PATCH_DIR}/branch-javac-${fn}.txt" ]]; then                                                                                 
        ${GREP} '\[WARNING\]' "${PATCH_DIR}/branch-javac-${fn}.txt" \                                                                         
          > "${PATCH_DIR}/branch-javac-${fn}-warning.txt"                                                                                     
      else                                                                                                                                    
        touch "${PATCH_DIR}/branch-javac-${fn}.txt" \                                                                                         
          "${PATCH_DIR}/branch-javac-${fn}-warning.txt"                                                                                       
      fi                                                                                                                                      
                                                                                                                                              
      ${GREP} '\[WARNING\]' "${PATCH_DIR}/patch-javac-${fn}.txt" \                                                                            
        > "${PATCH_DIR}/patch-javac-${fn}-warning.txt"                                                                                        

But ant's warning output format is as follows:

[javac] /home/sekikn/pig/src/org/apache/pig/backend/hadoop/executionengine/mapReduceLayer/JobControlCompiler.java:64: warning: [deprecation] ComparisonFunc in org.apache.pig has been deprecated
