Just installed Windows 10 and Eclipse no more starts

问题

I just upgraded from Windows 8 to Windows 10 (both 64-bit) and my previous Eclipse Juno with ADT-plugin for Android development is no longer starting.

All I can see is the mouse pointer showing that something is loading for a few seconds and then nothing else happens.

What I tried

renamed eclipse.ini to let it recreate it: did not even recreate it, so renamed it back.
turned on "Windows 8" compatibility on Eclipse exe. No changes.
tried to look at workspaceDir/.metadata/.log. No entries about this.

What follows are the contents of eclipse.ini:


    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120913-144807
    -product
    com.android.ide.eclipse.adt.package.adtproduct
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    --launcher.defaultAction
    openFile
    -vmargs
    -Dosgi.requiredJavaVersion=1.6
    -XX:MaxPermSize=256m
    -Xms512m
    -Xmx1024m

And this is the Java version I have installed:


    C:\Users\user>java -version
    java version "1.8.0_51"
    Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
    Java HotSpot(TM) Client VM (build 25.51-b03, mixed mode)

I'm stuck. Where can I find more clues since I've still not found others experiencing the same issue?

回答1:

Solved.

Just uninstalled completely Java and JDK (also manually deleted "Java" folder in "C:\ProgramFiles") and downloaded and reinstalled the very same version of JDK Windows x64 from here, and everything works again now.

回答2:

I solved this problem by first reinstalling java, then removing PATH variable "C:\ProgramData\Oracle\Java\javapath" and resetting the PATH variable for JDK. steps for setting path variable:

go to control panel
double click "system"
click on "Advanced system setting"
click on "environment variable"
select "path" and click on "edit"
remove "C:\ProgramData\Oracle\Java\javapath"
reset JDK path as "C:\Program Files\Java\jdk1.8.0_65\bin" and "C:\Program Files\Java\jdk1.8.0_65\lib\tools.jar"
click ok
restart eclipse. resolved. Here my PC java version is 1.8.0_65. Your may be different. But set path as your JDK version.

回答3:

I was also having the same problem.I just checked my java version as stated above it was showing 1.8.0 so I just removed the "C:\ProgramData\Oracle\Java\javapath;" form the system variable and it solved my problem.

回答4:

I was having the same problem but i didn't uninstall java, i just set the java variable in system settings and it worked fine

回答5:

You don't need to uninstall java. Just remove the following line from your environment(system) variables, which will be in starting of path variable. Windows 10 is keeping a copy of all your program files in ProgramData folder location .To confirm, Check the java version from your command line before and after change. It worked for me...

"C:\ProgramData\Oracle\Java\javapath;"

回答6:

I had my Java path set correctly in eclipse.ini but forgot to check "bitness" of eclipse and JVM. These have to pair (32 bit or 64 both) otherwise eclipse fails to start without error or message.

It is a foolish error but not so obvious when upgrading, so maybe this saves someone else few minutes or more...

回答7:

Retain single version of java and uninstall all other versions
and update the eclipse.ini text file as below but change the java path and versions appropriately.
