[MyEclipse] pop-up window error errors running builder ' Deployment.

reproduced , previously saved locally, and now moved up, I don't know where Yumbo is.

1. After modifying the Java source code, click Save, the IDE automatically compiles and hot deploy, prompt the following error:

Errors occurred during the build.
Errors running builder ' Deploymentbuilder ' on Project name '.
Java.lang.NullPointerException

Cause:

The IDE checked the automatic compilation deployment, which produced an exception when the call was deployed.

Workaround:

To cancel the automatic deployment of MyEclipse:
Right click on the item->properties, Builders, and remove the Deploymentbuilder check box.

This way, the system will not be automatically hot deployed, you can click on the toolbar of the Deploy MyEclipse ee ... For manual deployment.

Two. ( recommended )

2. First close the MyEclipse workspace.

   this file. Some deployment project information is stored in this file. There is no error in deleting the information for this deployed project.

6. Restart the boot MyEclipse to resolve .
