如何更改所有Eclipse工作区的默认JRE？ [英] How to change default JRE for all Eclipse workspaces?

问题描述

我在 C：\Program Files（x86）\Java\jre6 中有一个JRE，这是我安装Eclipse时唯一的JRE。我随后在 C：\home\SFTWR\jdk1.6.0_21 中安装了一个完整的JDK，并更改了我的 JAVA_HOME 环境变量。但是，每次启动新的Eclipse工作区时，它只会选择旧的JRE，我必须手动删除它并添加新的JRE。

I have one JRE in C:\Program Files (x86)\Java\jre6 and that was the only one at the time I installed Eclipse. I have subsequently installed a complete JDK in C:\home\SFTWR\jdk1.6.0_21 and changed my JAVA_HOME environment variable to that. However, every time I start a new Eclipse workspace, it only picks up the old JRE and I have to manually remove it and add the new one.

如何将Eclipse安装绑定到新的JDK，以便每个新工作区只指向？我检查了 eclipse.ini ，但没有参考到哪个JRE去。

How do I bind my Eclipse install to the new JDK so that every new workspace points to that only? I checked eclipse.ini but there was no reference there to which JRE to go to.

更新：

我进了 Prefs-> Java->安装的JRE 新位置，将其标记为默认值，删除另一个，它仅对当前工作空间有效。但是，当我打开一个新的工作区时，只有旧的JRE可用。所以这并没有改变适用于所有（至少新的）工作空间的核心Eclipse配置

I went into Prefs->Java->Installed JREs, added the new location, marked it as default, removed the other, and it was effective only for the current workspace. However, when I opened a new workspace, only the old JRE was available. So this didn't change the core Eclipse config that is applicable across all (at least new) workspaces

推荐答案

最后得到它： Eclipse接收JRE的方式是使用系统的PATH 。

我没有 C：\home\SFTWR\jdk1.6.0_21\bin 以前的路径，我确实有 C：\Program Files（x86）\Java\jre6\bin 。我已经将 JRE_HOME 和 JAVA_HOME 设置为 C：\home\SFTWR\ jdk1.6.0_21 ，但这两个都不重要。我猜Eclipse（在UNIX / Linux上）（或哪个）可以看到Java在路径中的位置，并将JRE java.exe 属于。在我的情况下，尽管我完成了所有的配置调整（包括上面提到的 eclipse.ini -vm选项），但它仍然停留在路径中。

I did not have C:\home\SFTWR\jdk1.6.0_21\bin in the path at all before and I did have C:\Program Files (x86)\Java\jre6\bin. I had both JRE_HOME and JAVA_HOME set to C:\home\SFTWR\jdk1.6.0_21 but neither of those two mattered. I guess Eclipse did (something to the effect of) where java (or which on UNIX/Linux) to see where Java is in the path and took the JRE to which that java.exe belonged. In my case, despite all the configuration tweaks I had done (including eclipse.ini -vm option as suggested above), it remained stuck to what was in the path.

我从路径中删除了旧的JRE bin，将新的JRE bin放入，它适用于所有工作区。

I removed the old JRE bin from the path, put the new one in, and it works for all workspaces.
