Created attachment 565894 [details] simple example to reproduce the bug Description of problem: When the exec outputproperty task is used twice with the same outputproperty name, the outputproperty keeps the value of the first execution. This was not true in prior versions, and is badly breaking my ant scripts. The obvious workaround not to use the same outputproperty name twice does not work, because there is no clear way to do that within a loop. Version-Release number of selected component (if applicable): ant-1.8.2-6.fc16.noarch How reproducible: 100% Steps to Reproduce: 1. ant -f test.xml 2. ant -f test2.xml 3. Actual results: [briemers@briemersw ant]$ ant -f test.xml test Buildfile: /autohome/docbill/workspace/reports.fte2/ant/test.xml test: [echo] value = a [echo] value = a [echo] value = a BUILD SUCCESSFUL Total time: 1 second [briemers@briemersw ant]$ ant -f test2.xml Buildfile: /autohome/docbill/workspace/reports.fte2/ant/test2.xml test: [echo] value = a [echo] value2 = a [echo] value = b [echo] value2 = a [echo] value = c [echo] value2 = a BUILD SUCCESSFUL Total time: 1 second Expected results: [briemers@briemersw ant]$ ant -f test.xml test Buildfile: /autohome/docbill/workspace/reports.fte2/ant/test.xml test: [echo] value = a [echo] value = b [echo] value = c BUILD SUCCESSFUL Total time: 1 second [briemers@briemersw ant]$ ant -f test2.xml Buildfile: /autohome/docbill/workspace/reports.fte2/ant/test2.xml test: [echo] value = a [echo] value2 = a [echo] value = b [echo] value2 = b [echo] value = c [echo] value2 = c BUILD SUCCESSFUL Total time: 1 second Additional info:
Created attachment 565895 [details] loop example that also reproduces the bug
Note: The simple example is "test.xml", and the loop example is "test2.xml".
It looks like this is more complicated than it appears. I downgraded ant rpms to the fedora 15 versions, and ran into the same problem, even though it worked for me when I was still using fedora 15. This suggest the problem is not ant itself but a change in a dependency it uses.
OK. I've been reading through various documentation. It looks to me the bug is the older versions that where buggy. In ant properties are suppose to be immutable, but somehow in Fedora 15 and prior the immutable aspect was not enforced. I am guessing something was corrected in the openjdk to correct this. I can update my ant scripts to use the local task, and that resolves the problem. Sorry for taking your time with this.
