when eclipse is flashed after double-clicking Eclipse, there are a couple of reasons:1. Environment configuration issues (usually in the new environment), the workaround:
(1) Check that the Java environment variables are configured well (2) to see if Eclipse has the same number of bits as the JDK (for example, the JDK is 64 bits, and Eclipse is 32 bit is problematic and should be consistent between the two digits. Either 32-bit or 64-bit)
(3) Check the Eclipse.ini configuration file for problems, specific configuration method and parameter information on the Internet a lot, here is not detailed (general Eclipse comes with the Can)
2. The last time Eclipse was closed unexpectedly, workspace problem, the problem of this situation is slightly complex, more difficult to solve, you can try the following scenarios: Solution One :
Locate the Your_workspace/.metadata/.plugins/org.eclipse.core.resources/.snap file, and then remove it to try to resolve the issue.
Solution Two:
Enter your_workspace/.metadata/.plugins/ (1) Rename org.eclipse.core.resources to Org.eclipse.core.resources_old (2) Double-click Eclipse to start, and then close (3) Delete org.eclipse.core.resources and Org.eclipse.core.resources_old Change back to org.eclipse.core.resources solution Three:
go to the your_workspace/.metadata/directory and locate the. log file. (1) Open a. log file and find it! MESSAGE at the beginning of a line (usually there will be more than one line, only see the top one or two, generally in the 10th line of the file ), this line shows the reasons for not starting up, I have to share the situation I encountered, we can follow the same ideas to find the problem.
(2) Analysis according to the log:
Situation one:! MESSAGE the workspace exited with unsaved changes in the previous session; Refreshing workspace to recover changes. See this log, you need to turn you off unexpectedly before you change the project in your_workspace/.metadata/.plugins/ The org.eclipse.core.resources/.projects/directory is found and deleted, and then restarted after deletion.
situation two:! MESSAGE projectopenedwithworkspace:failed to find manifest package for project Androiddemo. This is generally when the use of the situation, the same three projects may be abnormal close before the change, but not sure that is the cause of eclipse does not come, the two or three projects are deleted. So in the face of such a problem is not eager to delete the two or three, to the two or three possible changes in the project back out, a try, but in the end the project changes caused.
situation three:! MESSAGE An error occurred while automatically activating bundle Com.android.ide.eclipse.adt (2). If this is the sentence in the log, find Your_workspace\.metadata\.plugins\org.eclipse.e4.workbench/workbench.xmi and Delete the file to restart
The above is my solution to eclipse, a flash over the problem, I hope to help you.
Eclipse doesn't open, it's a flash.
