Subject [jira] [Created] (HADOOP-12188) javac warning file is always empty on ant-based projects
Date Mon, 06 Jul 2015 01:46:04 GMT
Kengo Seki created HADOOP-12188:
-----------------------------------

             Summary: javac warning file is always empty on ant-based projects
                 Key: HADOOP-12188
                 URL: https://issues.apache.org/jira/browse/HADOOP-12188
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: yetus
            Reporter: Kengo Seki


(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:

{code}
      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"                                
                                                       
{code}

But ant's warning output format is as follows:

{code}
[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
{code}
