在Windows 7上运行Eclipse没有找到JRE和JDK [英] Running Eclipse on Windows 7 JRE and JDK not found

问题描述

我在Windows 7上下载了最新的Eclipse。当我点击eclipse图标时，会抛出以下异常：

我已经安装了JRE和JDK。

更新：Eclipse.ini内容：

  -startup 
 plugins / org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar 
 --launcher.library 
 plugins / org.eclipse.equinox.launcher.win32.win32.x86_1.1.200。 v20120913-144807 
 -product 
 org.eclipse.epp.package.jee.product 
 --launcher.defaultAction 
 openFile 
 --launcher.XXMaxPermSize 
 256M 
 -showsplash 
 org.eclipse.platform 
 --launcher.XXMaxPermSize 
 256m 
 --launcher.defaultAction 
 openFile 
  - vmargs 
 -Dosgi.requiredJavaVersion = 1.5 
 -Dhelp.lucene.tokenizer = standard 
 -Xms40m 
 -Xmx512m 
 -vm C：\Program文件（x86） \Java\jre7\bin 
  

解决方案

根据Eclipse文档中，您可能需要在虚拟机引用之前指定之前的VM ，并且路径不应与-vm开关在同一行上。

• -vm选项及其值（路径）必须是单独的行。


• 该值必须是Java可执行文件的完全绝对路径或相对路径，而不仅仅是Java主目录。


• -vm选项必须位于-vmargs选项之前，因为-vmargs之后的所有内容都将直接传递到JVM。

来源：Eclipse Wiki例如：

  -vm 
 C：\Java\JDK\1.6\bin\javaw.exe 
 -vmargs 
 -Dosgi.requiredJavaVersion = 1.5 
 -Xms40m 
 -Xmx1024m 
  

您还可能需要围绕路径与一些引号，因为它包含空格。始终在根目录下安装不带空格的Eclipse和Java，而不是在 Program Files 之下，以避免此问题。

I downloaded the latest Eclipse on Windows 7. When I click the eclipse icon it throws the following exception:

I have already installed JRE and JDK.

UPDATE: Eclipse.ini contents:

   -startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120913-144807
-product

-showsplash

openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m
-vm C:\Program Files (x86)\Java\jre7\bin

解决方案

According to the Eclipse documentation, you may need to specify the VM before the VM args, and the path should not be on the same line as the -vm switch:

• The -vm option and its value (the path) must be on separate lines.
• The value must be the full absolute or relative path to the Java executable, not just to the Java home directory.
• The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM.

For example:

-vm
C:\Java\JDK\1.6\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx1024m

You also might need to surround your path with some quotes, since it contains spaces. I always install things like Eclipse and Java in root directories with no spaces, not under Program Files, to avoid this problem.
