While running an automatic build on an EJB project, I am getting an error that states:

‘Errors occurred during the build. Errors running builder ‘Integrated External Tool Builder’ on project ‘myproject’. The builder launch configuration could not be found.’

The build works fine when building any of the other non-EJB projects.

Any ideas?

shanr5 ,

Sorry that you are seeing this issue with MyEclipse.

1) Can you paste the Build Id here from Help > About MyEclipse Blue Edition > Build Id?

2) Have you renamed the external tool builder? If you rename an existing external tool builder that is configured to run during auto-builds, you will get the following error: Errors during build. Errors running builder “Integrated External Tool Builder” on project <PROJECT_NAME>. The builder launch configuration could not be found. The workaround is to first disable the builder for auto-builds and then rename the builder.

3) Can you do a clean on the project and check if the build runs fine ?

4) Go to Project->Properties->Builders to see which builder your project is using.

5) Clear the contents of the .log which is located at <workspace dir>/.metadata/.log. Now replicate the issue and paste the contents of the .log file here for me.

Let me know how this works for you.

1) Version: 9.1 Blue – Build id: 9.1-Blue-20110701

2) I have not renamed the builder.

3) I get the same error when I clean and build

4) In my project properties, I have 3 builders listed: Faceted Project Validation Builder, Java Builder, and Validation

5) .log contents:

shanr5,

Thank you for the details. I could not replicate the issue at my end.

1) Can you please create a dummy EJB project of the same spec level using the ejb wizard and check if you see the same issue ?

2) It appears that your project is associated with external builders. Can you paste the .project file here for us ?

[shanr5]

1) I’m working on it.

2) The contents of the .project file for the ejb project follows:

[shanr5]

I removed the ExternalToolsBuilder from my .project and it builds fine now. I believe it was associated with an external builder like you said, and I’m not sure why. This was converted from a RAD project.

Thanks for your help.

shanr5 ,

Glad that it is working.
