I can't write the all code but it's something like that if you could help me please
回答1:
Make sure your JDK is also 64-bit, and make sure the version of Eclipse you have downloaded is 64-bit. If everything is not aligned (system, JDK, IDE) as 64-bit you will get all kinds of strange errors and your IDE will not start.
UPDATE:
The issue occurs when you are installing a plug-in.
Please see this post:
- Error when try install plugin
Or, if you don't want to do through all that, I suggest downloading a bare-bones version of Eclipse (no PD2 plugins built-in, just generic) and using the Marketplace to grab the extra plug-ins you want manually.
回答2:
if the problem is still not resolved even after ensuring you have the right JDK installed for your machine, try using the advanced mode located under the overflow menu on the right-hand side of the eclipse installation window. This installation mode worker for me and several of my friends. You can also follow the video here
