If you have installed a new jdeveloper (11g) and got some error like this, while compiling or deploying a SOA project. 

 ant-sca-compile.xml does not exist

it will eventually fail the compiliation and also will not allow any soa deployment, to SAR or directly on weblogic server.

It normally happen, when during the installation there is any issue comes and jdev try to fix it, by modifying allready installed files and make them backup.

Solution 

go to the folder middleware\jdeveloper\bin and now check files with the .backup extension. Remove all extension from there and your jdev will be available to use.

If issue still presists then remove your system folder and restart jdev and try to compile again.

Most of the time your issue should be solved by now.
