http://issues.apache.org/bugzilla/show_bug.cgi?id=28419 Jar task removes existing read-only destfile when permission is denied to overwrite Summary: Jar task removes existing read-only destfile when permission is denied to overwrite Product: Ant Version: 1.6.1 Platform: Sun OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I've encountered an issue with the Jar task, evidenced by the sequence contained in the sample build.xml content below: ===== BEGIN build.xml <?xml version="1.0" encoding="UTF-8"?> <project basedir="." default="bugdemo" name="Jar deletion bug demo"> <target name="bugdemo"> <echo message="Remove any existing jar file" /> <delete file="bugdemo.jar" /> <exec executable="/bin/ls"> <arg value="-la" /> <arg value="bugdemo.jar" /> </exec> <echo message="Create a read-only jar file" /> <touch file="fileone"/> <jar basedir="." includes="fileone" destfile="bugdemo.jar" /> <chmod file="bugdemo.jar" perm="444" verbose="true" /> <exec executable="/bin/ls"> <arg value="-la" /> <arg value="bugdemo.jar" /> </exec> <echo message="Try to overwrite the read-only jar file" /> <touch file="filetwo"/> <jar basedir="." includes="filetwo" destfile="bugdemo.jar" /> <!-- This line not reached... --> <exec executable="/bin/ls"> <arg value="-la" /> <arg value="bugdemo.jar" /> </exec> </target> </project> ===== END build.xml When executed, the above produces the following output: ===== BEGIN OUTPUT Buildfile: build.xml bugdemo: [echo] Remove any existing jar file [exec] bugdemo.jar: No such file or directory [exec] Result: 2 [echo] Create a read-only jar file [jar] Building jar: /home/mcumings/cvs/swie/Project/jaxb/bugdemo.jar [chmod] Applied chmod to 1 file and 0 directories. [exec] -r--r--r-- 1 mcumings staff 418 Apr 15 14:08 bugdemo.jar [echo] Try to overwrite the read-only jar file [jar] Building jar: /home/mcumings/cvs/swie/Project/jaxb/bugdemo.jar BUILD FAILED /home/mcumings/cvs/swie/Project/jaxb/build.xml:23: Problem creating jar: /home/mcumings/cvs/swie/Project/jaxb/bugdemo.jar (Permission denied) Total time: 6 seconds ===== END OUTPUT The problem lies in the fact that in the process of failing, the Jar task seems to like to remove the read-only jar file target, as evidenced in the following output of 'ls -la': ===== BEGIN OUTPUT total 25 drwxr-xr-x 2 user staff 512 Apr 15 14:08 ./ drwxr-xr-x 33 user staff 1024 Apr 14 12:22 ../ -rw-r--r-- 1 user staff 907 Apr 15 14:07 build.xml -rw-r--r-- 1 user staff 0 Apr 15 14:08 fileone -rw-r--r-- 1 user staff 0 Apr 15 14:08 filetwo ===== END OUTPUT My use of Ant in this case is a bit out of the ordinary, but read/write permissions setup by the operating system should be observed and handled properly within Ant. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
