How do I set the Java path in Eclipse so I can run it on an external drive?
提问by PHLAK
I have Eclipse 3.5.1 and Java Portable (from Portableapps.com) installed on a portable hard drive and would like to point my Eclipse to use the portable apps Java version. This will allow me to use Eclipse on a computer even if Java isn't installed. How do I accomplish this?
我在便携式硬盘驱动器上安装了 Eclipse 3.5.1 和 Java Portable（来自 Portableapps.com），并希望让我的 Eclipse 使用便携式应用程序 Java 版本。即使未安装 Java，这也允许我在计算机上使用 Eclipse。我该如何实现？

Perhaps take a look at the Eclipse Portableproject on SourceForge
也许看看SourceForge 上的Eclipse Portable项目
EDIT: Alternatively, edit the eclipse.inifile and add:
编辑： 或者，编辑eclipse.ini文件并添加：
-vm
..\path-to-jre\bin\javaw.exe
[The new line after -vm matters]
[-vm 后面的新行很重要]

Open Eclipse.
打开日食。
Navigate to Window > Preferences > Java > Installed JREs
导航到“窗口”>“首选项”>“Java”>“已安装的 JRE”
Add the JRE on your portable hard drive
在您的便携式硬盘驱动器上添加 JRE
Set this as your default JRE.
将此设置为您的默认 JRE。

I know it's been ages since this post has been active, but I might have three additional details to contribute (at least they seemed to be crucial in my case):
我知道这篇文章已经活跃很久了，但我可能还有三个额外的细节要贡献（至少在我的情况下它们似乎是至关重要的）：
- Just as stated here, paths need to be separated by
/, not\ineclipse.ini At least on MS Windows 7 (64 bit), it seems to be very important that you put the
-vm ../path-to-jre/bin/javaw.exeat the very beginningof theeclipse.inifile and that it is actually twolines:-vm
../path-to-jre/bin/javaw.exe
Otherwise Eclipse seems to first try to find
C:\Windows\System32\javaw.exewhich will cause an error (at least my error log says so)- Seems that the following path (found here) also works:
../path-to-jre/bin/server/jvm.dll
- 正如此处所述，路径需要由
/,而不是\in分隔eclipse.ini 至少在微软Windows 7（64位），这似乎是非常重要的，你把
-vm ../path-to-jre/bin/javaw.exe在最开始的的eclipse.ini文件，它实际上是2线：-vm
../path-to-jre/bin/javaw.exe
否则 Eclipse 似乎首先尝试查找
C:\Windows\System32\javaw.exe哪个会导致错误（至少我的错误日志是这样说的）- 似乎以下路径（在这里找到）也有效：
../path-to-jre/bin/server/jvm.dll
As of 2013-04-19 for Eclipse 4.2.2 (Juno), this is how my eclipse.inilooks like:
截至 2013 年 4 月 19 日，对于 Eclipse 4.2.2 (Juno)，这就是我的eclipse.ini样子：
-vm
c:/jre/Java64/bin/javaw.exe
-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
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Xms40m
-Xmx512m
Note that /Java64/bin/javaw.exeis taken from portable java
请注意，/Java64/bin/javaw.exe取自便携式 java
