Breakpoints doesn't hit if create Project from existing source. [EBZ#439778] ---------------------------------------------------------------------------- Key: ERT-342 URL: https://issues.jboss.org/browse/ERT-342 Project: Eclipse Release Train Issue Type: Task Components: JSDT Reporter: Friendly Jira Robot Assignee: Ilya Buziuk Labels: Debug, bzira Fix For: Neon.1 (4.6) I created JavaScript project (Name: Sample) using "Create Project from existing source" Let see in "C:\TestProject" which contains test.js script. Now i opened test.js and added some breakpoint in that script, now when I'm running the script breakpoint is Not Hitting. *****************Investigation******************** org.eclipse.wst.jsdt.debug.internal.core.model.ScriptResolutionManager there is a function guessScriptMatches(ScriptReference script, IPath path). JavaDoc of this function: "Guesses if the paths are considered equal by walking backward from the last segment of the paths and counting the matching segments. The paths are guessed to be equal iff any two or more segments match in order." So in My case because Project name and physical folder name are different. That why only file name is matching, but this function is checking for at least 2 segment to match, so it returns false and caller function will not add JavaScriptDebugTarget for this script. ******************** Solution Proposal********************* We can check if current script is inside root folder of project then if one segment matches we'll return true, for other case it will remain check for at least two segment to match
