Eclipse - An Error Has Occured

Question

For some reason I'm no longer able to fire up eclipse as every time I open it, i get an error that states : An error has occures, see log file x.log

• I looked around online for this issue and one of the things that seamed to have solved it is by deleting all .snap files from .metadata.plugins\\org.eclipse.core.resources folder but I couldn't find any .snap files (PS: this is now a clean install of eclipse)

• I also tried re-installating JDK and JRE

java version "1.8.0_11" Java(TM) SE Runtime Environment (build 1.8.0_11-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

• I also tried running eclipse with cmd with eclipse - clean command but same error pops up.

I'm very new at this..can you please tell me what I'm doing wrong :)

Here's the log file:

Answer 1

Try to delete the .metadata file and again restart the eclips with the workspace. Due to some changes the metadata may be holding the older information related to eclipse and workspace.

Answer 2

安装JDK 1.9后，出现此错误并将其更改为1.8。

Answer 3

您应该将jdk更改为1.8，就可以了。
