Eclipse无法启动

Question

When I try to start Eclipse Juno on Windows 7 a messagebox saying "An error occured. See the log file" appears and eclipse won't start. I tried either renaming my workspace folder or change eclipse workspace settings stored in eclipse_root_folder\\configuration.settings\\org.eclipse.core.net.prefs but it doesn't work. I have been using this for 2 months and this didn't happen before. Any solution?

• I have the latest version of java
• /eclipsepath/eclipse.exe -clean [this isn't working]
• I haven't made any changes on my pc

Answer 1

Eclipse stores a copy of your project in it's cache. It can happen when Eclipse crashes (that happens) that this cache is corrupted and thus Eclipse won't start again. Starting with '--clean' somethimes fixes this but not always.

In my experience one solution is to delete the project's cache. Look for the '.metadata' folder in your workspace and delete it while Eclipse is NOT running (make a backup just in case). Then launch Eclipse again.

You may loose your Run Configurations preferences which you can then restore from your backup copy of ".metadata/.plugins/org.eclipse.debug.core/.launches".

Answer 2

尝试在命令提示符中执行以下行：

/eclipsepath/eclipse.exe -clean

Answer 3

eclipse.buildId=M20120914-1800 java.version=1.6.0_25 java.vendor=Sun Microsystems Inc. BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US Framework arguments: -product org.eclipse.epp.package.jee.product Command-line arguments: -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.jee.product

No you don't have latest version of java, your eclipse is using java 1.6, Latest java is 1.8

There seems to be some mismatch ie. OS is win32 and arch is x86_64. Make sure that if OS is 32 bit, Java and Eclipse is also 32 bit

Answer 4

Are you sure you downloaded the Eclipse/ JAVA version for the right processor architecture?
Looks like try to run a mixture of 32-bit and 64-bit applications on your system, maybe you updated your eclipse/ java/ etc. or added some new library?

Answer 5

You're probably not using the version of Java that you think you are. You need to specify to Eclipse what JVM to use, via eclipse.ini . Otherwise it can pick up unintended versions from your system path.

Answer 6

in your files manager do the following thing.

rm YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.snap

rm /home/anoop/workspace2/.metadata/.plugins/org.eclipse.core.resources/.snap

Answer 7

在终端中运行以下命令

/full/path/to/second/eclipse -clean

Answer 8

When even "clean" command fails, I have had good results with

eclipse -clean -cleanPersistedState

Apart from that, I'd use FileMon by SysInternals (or ProcMon, or similar utility) to try and see what operation exactly is failing, or where is Eclipse looking for its data.

Answer 9

Answer 10

Have you tried a restore of your computer to yesterday? It's certainly not as elegant as some of these other answers, but I bet something changed that you're just not thinking about (or noticing - background update, perhaps?), and a restore will fix whatever that was.
