 | Known Issue
When stopping a build, QuickBuild currently relies on JVM's process facility to kill the spawned build process (by calling Process.destroy). However this mechanism has a big limitation that it only kills the direct spawned build process. Any spawned child processes of the build process will still be running. For example, if the build script invokes a batch (or shell script) file, and the batch file calls javac to compile the code, stopping the build only terminates executing of the batch process while leaving javac process intacted. In this case, you will need to manually kill any spawned child processes. In the same time, we are investigating other approaches to work around this issue. |
