Hello,

since I updated to MyEclipse 9 I have the following problem: I have a project, where I sometimes need to upgrade certain jar-files with a newer version. This is not possible with MyEclipse 9 because it seems to hold exclusive file access to the project jar-files. When I try to copy my newer version into the project, I get an error message:

“An exception has been caught while processing the refactoring ‘Copy’.

Reason:
Problems encountered while deleting resources”

When I try to do this from outside eclipse in Windows Explorer, I get the error message that the file is currently in use.

I tracked this down with Process Explorer and figured out that MyEclipse is holding access to these files. In earlier versions I never had problems with upgrading jar-files in a project.

ifmEssen,

1) Can you share your build id from Help > About MyEclipse Enterprise Workbench ? Paste it here for me.

2) How did you install ME 9.0 ? Is it through Pulse/All-In-One installer/Archived Update site?

3) Are you running on Windows OS ? Did you install any third party plugins like SpringSource Tool Suite(STS )?

4) Can you check if the same issue exists for .java/.html/.jsp files too?

5) Clear the contents of the .log file which is located at <workspace dir>/.metadata/.log.Can you shutdown the IDE, start it with -clean option and check if the issue persists ?
Here is an FAQ on starting ME with -clean :
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/

6) Check for any errors logged in the .log file. Paste them here for me.

Let me know how this works for you.

1) Build id: 9.0-20110318
2) I installed the All-in-one package on a new system
3) I am running Windows 7 professional. No SpringSource Tools installed.
4) Deleting java files or jsp’s is not a problem. Only experienced this with jars
5) Running MyEclipse with -clean option issues the same problem.
6) After trying to replace an existing jar file within my project with a newer version, the following was logged in the error log:

ifmEssen,

Thanks for the information.

Can you answer some more questions for me?

1) What kind of a project it is? Are the jars located in the WEB-INF folder?

2) When does this problem occur ? Is it straight after starting MyEclipse or after deploying the project or after running the project ?

3) How are you trying to replace the jar? Do you see the same issue if you do a copy in Windows but a paste in MyEclipse ?

[ifmEssen]

1) It is a web project built for liferay portal using the liferay-portal-sdk toolset. The “WebRoot” property is set to a folder called “docroot”. The jars are in the WEB-INF/lib folder.
2) The problem occurs in most cases straight after start of MyEclipse. However, I managed to copy the jars files one or two times when I did it directly after start. Cannot reproduce it now.
3) I tried to do copy&paste within MyEclipse. Interesting: When I use Windows Explorer for copy and paste the jar into MyEclipse, it seems to work. Nice workaround 😉

ifmEssen,

I am unable to replicate it at my end. Glad that the workaround works for you.
Do let us know if you have any other issues.
