Short Workspace Path Plugin
Use shallow directory hierarchy for build workspaces to avoid build failures on filesystems with constrained path length.
The plugin detects path length limitation for given node automatically and chooses to either use default (and potentially long) workspace path or hash based one with controlled length.
Plugin accepts Jenkins-wide configuration property
org.jenkinsci.plugins.shortwspath.BUILD_PATH_LENGTH (defaults to 512) representing the desired minimal path length available in the workspace (regardless of the path length to the workspace itself). Whenever default workspace will not leave enough room in path name for the build, workspace path is shortened. Note that this plugin does not provide strong guarantee that
BUILD_PATH_LENGTH will be always available, but it tries its best when it would not with the default algorithm.
The plugin has currently no effect on master node and never places short workspaces out of slave's workspace root.
