Hello, i have the sun jdk1.4.2 installed on my gentoo box. i also have the Eclipse 3.0M5 installed but they won't start. The following output will generated in the log: !ENTRY org.eclipse.core.launcher 4 0 Jan 26, 2004 08:20:20.32 !MESSAGE Exception launching the Eclipse Platform: !STACK java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.internal.boot.InternalBootLoader.startup(InternalBootLoader.java:1049) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoader.java:838) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:461) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.launcher.Main.basicRun(Main.java:299) at org.eclipse.core.launcher.Main.run(Main.java:767) at org.eclipse.core.launcher.Main.main(Main.java:601) Caused by: org.eclipse.core.runtime.CoreException: Unable to create platform lock file: /home/ally/.eclipse/workspace/.metadata/.lock. at org.eclipse.core.internal.runtime.InternalPlatform.createLockFile(InternalPlatform.java:228) at org.eclipse.core.internal.runtime.InternalPlatform.loaderStartup(InternalPlatform.java:641) ... 14 more
Please see bug 44735 for problem description and workaround. If your workspace is not mounted on a NFS file system, please reopen. *** This bug has been marked as a duplicate of 44735 ***
My workspace is not on a nfs drive, it is local on my harddrive
Could you try the test case that appears in bug 44487 comment 9 and tell us what happens? If that does not work for you, then, for some reason, Java file locking does not work on your platform. The alternative would be to disable file locking by passing the "org.eclipse.core.runtime.ignoreLockFile" property: eclipse -vm <JAVA_HOME>/bin/java -vmargs -Dorg.eclipse.core.runtime.ignoreLockFile
With the testprog i get the following output: bash-2.05b$ java TestLock /tmp/bar.txt trying to acquire lock once Exception in thread "main" java.io.IOException: Value too large for defined data type at sun.nio.ch.FileChannelImpl.lock0(Native Method) at sun.nio.ch.FileChannelImpl.tryLock(FileChannelImpl.java:788) at java.nio.channels.FileChannel.tryLock(FileChannel.java:967) at TestLock.acquireLock(TestLock.java:8) at TestLock.main(TestLock.java:14) bash-2.05b$ after this i tried to start with the ignore lockfile args but eclipse won't start with the same error.
That confirms that the problem is caused by the VM/OS implementation of file locking, and you will be forced to disable the locking capability in Eclipse. About you not being able to disable file locking: you must ensure that the property is specified after -vmargs, because it is an argument to the VM. -data and -vm are arguments to Eclipse. <eclipse_install>/eclipse [arguments to Eclipse] -vmargs [arguments to the VM] If it still does not work for you, could you please copy and paste the exact command line you are using to run Eclipse? Thanks.
Thanks a lot, now eclipse is starting up. I have to disable the filelocking and then it works
