Ant + Vista 64:“无法定位 tools.jar"；(jre/jdk 冲突?) [英] Ant + Vista 64 : "Unable to locate tools.jar" (jre/jdk conflict?)

问题描述

我正在尝试在 vista 64 环境中使用 ant 来构建一些 docbook/xml 文件.

I'm trying to use ant in a vista 64 environment to build some docbook/xml files.

但是，我无法解决此错误消息.有人有建议吗?

However, I can't resolve this error message. Anybody have suggestions?

C:\Users\Robert Admin>ant无法找到 tools.jar.预计在 C:\Program Files\Java\jre6\li 中找到它b\工具.jar构建文件:build.xml 不存在！构建失败

C:\Users\Robert Admin>ant Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\li b\tools.jar Buildfile: build.xml does not exist! Build failed

搜索了一下，我看到这个tools.jar消息是ant找不到jdk的结果.其实C:\Program Files\Java\jre6\lib\tools.jar 是与另一个程序一起安装的 JRE(我猜).Tools.jar 位于:C:\Program Files\Java\jdk1.6.0_22\lib

Googling around, I see that this tools.jar message is the result of ant not being able to find the jdk. In fact, C:\Program Files\Java\jre6\li b\tools.jar is a JRE installed with another program (I'm guessing). Tools.jar is located here: C:\Program Files\Java\jdk1.6.0_22\lib

我似乎无法告诉 Ant 查看 JDK 路径，只能查看已经存在的 JRE 路径.(从 Ant 文档来看，似乎 JRE 是不够的).

I can't seem to tell Ant to look in the JDK path, only the JRE path which was already there. (Judging from the Ant documentation, it seems that JRE is insufficient).

C:\Users\Robert Admin>echo %JAVA_HOME%

C:\Program Files\Java\jdk1.6.0_22\bin

C:\Users\Robert Admin>ant

更新 #1.我尝试卸载 64 位 jdk 并安装 32 位 jdk.结果:

Update #1. I tried uninstalling the 64 bit jdk and installing the 32 bit jdk. Result:

推荐答案

我在 64 位 Windows 7 机器和 Ant 1.8.2 上遇到了这个问题.解决方案是使用#bigfix 提到的管理工具来设置环境变量.按照适用于 Windows 的 Ant 安装说明进行操作.但不要将路径设置为 %ANT_HOME%\bin.而是使用显式路径，例如 C:\jdk-1.5.0.05\bin.

I had this problem on a 64-bit Windows 7 machine and Ant 1.8.2. The solution was to use the admin tools mentioned by #bigfix to set the environment variables. Follow the Ant installation instructions for Windows. But do not set the path as %ANT_HOME%\bin. Instead, use an explicit path such as C:\jdk-1.5.0.05\bin.

我的第一次测试失败了，因为我的命令窗口已经打开并使用旧的环境变量.关闭它并打开一个新的.然后尝试测试.它对我有用.

My first test failed because my command window was already open and using the old env vars. Close it and open a new one. Then try the test. It worked for me.
