初始化VM时出错（java / lang / NoClassDefFoundError：java / lang / Object）

I'm trying to install Java to use Eclipse (I followed all instructions to install Java and Eclipse) but my Eclipse is not starting due to some bad configuration I guess. I can't figure out why it's not working for me.

我正在尝试安装Java来使用Eclipse(我按照所有说明安装了Java和Eclipse)但是我的Eclipse由于一些错误的配置而无法启动。我无法弄清楚为什么它不适合我。

Eclipse Installation:

1. Extracted Eclipse at C:\eclipse

在C:\ eclipse中提取Eclipse

2. Created a shortcut to my desktop having target C:\eclipse\eclipse.exe

创建了具有目标C:\ eclipse \ eclipse.exe的桌面快捷方式

When I try to run Eclipse with this shortcut, I see following Eclipse splash screen for a second and it disappears. Eclipse does not start at all.

当我尝试使用此快捷方式运行Eclipse时,我会看到关注Eclipse启动画面一秒钟后它会消失。 Eclipse根本没有启动。

JAVA Installation:

1. Installed JDK at C:\Program Files\Java\jdk1.7.0_10

在C:\ Program Files \ Java \ jdk1.7.0_10安装了JDK

2. Installed JRE at C:\Program Files\Java\jre7

在C:\ Program Files \ Java \ jre7安装了JRE

Environment Variables Configuration:

环境变量配置:

JAVA_HOME = C:\Program Files\Java\jdk1.7.0_10
PATH = C:\Program Files\Java\jdk1.7.0_10\bin;

I tested my Java installation using the console and figured out this issue but I don't know how to fix it, and I guess this is causing Eclipse not to start.

我使用控制台测试了我的Java安装并找出了这个问题,但我不知道如何修复它,我想这会导致Eclipse无法启动。

please try to execute java from

请尝试从中执行java

C:\Program Files\Java\jdk1.7.0_10\bin

i.e from the location where java is installed.

即从安装java的位置。

If it is successful, it means that the error lies somewhere in the classpath.

如果成功,则表示错误位于类路径中的某处。

Not able to run Appium {“message”:”A new session could not be created. (Original error: ‘java -version’ failed

无法运行Appium {“message”:“无法创建新会话。 (原始错误:'java -version'失败

I used Jdk 1.8 and JRE 1.8, Classpath is also set properly but I observed that Java command gives Error to initialization of VM (java/lang/NoClassDefFoundError: java/lang/Object)

我使用了Jdk 1.8和JRE 1.8,Classpath也设置正确,但我观察到Java命令为VM的初始化提供了错误(java / lang / NoClassDefFoundError:java / lang / Object)

Uninstalled JRE and JDK completely 
Installed JRE 1.8 then
Installed JDK 1.8 
Set Classpath
check Java command works or not and its working 
also able to execute the Appium program thru Eclipse Kepler Service Release 2 with JDK1.8 support
