http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21636 Java task wraps output by default Summary: Java task wraps output by default Product: Ant Version: 1.6Alpha (nightly) Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The Java task when used with an 'output' attribute will wrap the output. This can lead to corruption/invalid output from otherwise well-behaving Java programs that emit all data on long lines without a newline. The output will have newlines added throughout in incorrect locations. A task snippet: <java classname="LongLine" output="longline.txt" /> where LongLine's main class will emit something greater than 4k without a new line to System.out. The output file longline.txt will now contain newlines in places not originally requested. The output from the above task would be different from: java LongLine > longline.txt It seems that the Redirector class will always print newlines. A partial fix is as follows: --- src/main/org/apache/tools/ant/taskdefs/Redirector.java Tue Jul 15 21:59:37 2003 +++ src/main/org/apache/tools/ant/taskdefs/Redirector.java.new Tue Jul 15 21:58:28 2003 @@ -365,7 +365,7 @@ if (outPrintStream == null) { outPrintStream = new PrintStream(outputStream); } - outPrintStream.println(line); + outPrintStream.print(line); } /** This is definitely not an ideal solution because now no newlines will be emitted to the file. This isn't right either, but solves my immediate problem. This problem also exists in Ant 1.5.3 which has the output code back in Java taskdef file. I'll leave it to people who know Ant better than I for a more complete solution. If you need a more precise reproduction case, please let me know, but it's fairly straightforward to reproduce (IMHO).
