Jenkins 1.6.42.1
Ubuntu 14.04
JAVA 7
Jenkins creates lots of warning message for matrix project. The size of log would just keep growing which makes it very hard to read.
The log looks something like this:
Feb 29, 2016 5:06:34 PM hudson.matrix.MatrixProject getRootDirFor WARNING: Cannot create directory /var/lib/jenkins/jobs/model/configurations/axis-BUILD_TYPE/release/axis-MODEL_NAME/XXX for the combination BUILD_TYPE=release,MODEL_NAME=XXXX Feb 29, 2016 5:06:34 PM hudson.matrix.MatrixProject getRootDirFor WARNING: Cannot create directory /var/lib/jenkins/jobs/model/configurations/axis-BUILD_TYPE/release/axis-MODEL_NAME/XXX for the combination BUILD_TYPE=release,MODEL_NAME=XXXX Feb 29, 2016 5:06:34 PM hudson.matrix.MatrixProject getRootDirFor
After some debugging, I think the problem is that it's calling File.mkdirs(), which would return false if the folder already exist.
public File getRootDirFor(@Nonnull Combination combination) { File f = getConfigurationsDir(); for (Entry<String, String> e : combination.entrySet()) f = new File(f,"axis-"+e.getKey()+'/'+Util.rawEncode(e.getValue())); if (!f.getParentFile().mkdirs()) { LOGGER.log(Level.WARNING, "Cannot create directory {0} for the combination {1}", new Object[]{f, combination}); } return f; }
I suggest there should be a check whether the folder exist. if !f.exists() && !f.getParentFile().mkdirs(), then output the warning.
