eclipse不会启动——没有找到java虚拟机。

Eclipse was running fine yesterday (and has been since I installed it about a year ago). Now all the sudden I'm getting the following error on startup:

Eclipse昨天运行良好(大约一年前我安装了Eclipse)。突然之间，我在启动时出现了以下错误:

"A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
C:\Program Files\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH"

I have not changed anyhing Eclipse/Java related on my machine but a Windows update was applied to my machine yesterday, so maybe that has something to do with it (but I don't see anything that would affect Java). I've looked at all the other posts about adding something to your PATH or adding the -vm option to the Eclipse ini (couldn't get this to work) or copying the jre folder to eclipse\jre (this worked but doesn't seem like a good long term solution). So I'm really trying to figure out how to get things back to the "default" setup without messing stuff up.

我没有在我的机器上修改任何与Eclipse/Java相关的东西，但是昨天我的机器上应用了Windows更新，所以这可能与它有关(但我没有看到任何会影响Java的东西)。我查看了所有其他关于在您的路径中添加一些东西的文章，或者将-vm选项添加到Eclipse ini(无法工作)或将jre文件夹复制到Eclipse \jre(这很有用，但看起来不像是一个很好的长期解决方案)。所以我真的想知道如何让事情回到“默认”的设置而不把事情弄得一团糟。

I'm running Windows 7, Eclipse Helios and Java 1.6.0_26.

我正在运行Windows 7, Eclipse Helios和Java 1.6.0_26。

Two ways to work around this .

有两种方法可以解决这个问题。

Recommended way : In your eclipse.ini file make sure you are pointing -vm to your jdk installation. More on this here .

推荐方式:在您的eclipse中。ini文件确保您将-vm指向您的jdk安装。更多内容在这里。
Pass in the vm flag from command line. http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F#Find_the_JVM

从命令行传入vm标志。http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F Find_the_JVM

Note : Eclipse DOES NOT consult the JAVA_HOME environment variable.

注意:Eclipse没有查询JAVA_HOME环境变量。

#2

Make sure both the Java version and Eclipse are belongs to same architecture.So install 64 bit java for 64 bit eclipse.

确保Java版本和Eclipse都属于相同的体系结构。因此，64位eclipse安装64位java。

#3

In my case i had few things missing. I didnt install JDK and JRE of 64 bit while eclipse was of 64 bit version. Once done and JDK\bin path was set in PATH variable eclipse worked fine :)

在我的案例中，我少了一些东西。我没有安装JDK和JRE 64位，而eclipse是64位版本。完成后，在path变量eclipse中设置了JDK\bin路径，效果很好:)

#4

eclipse.ini:

eclipse.ini:

--launcher.defaultAction  
--launcher.XXMaxPermSize  
256M  
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize<br/>
256m  
--launcher.defaultAction  
openFile  
-showsplash  
org.eclipse.platform
-vm
C:\Program Files\Java\jdk1.7.0_21\jre\bin\server\jvm.dll<br/>
--launcher.XXMaxPermSize  
256m  
--launcher.defaultAction  
openFile  
-vmargs  
-Dosgi.requiredJavaVersion=1.7

That worked for me. It doesnt have to be on the beginning, but surely it cant be on the end of the file.

为我工作。这并不一定要开始，但肯定不能在文件的末尾。
