Mac OS，JDK1.7(和1.8)不包含JNI_CreateJavaVM符号 [英] Mac OS, JDK1.7 (and 1.8) does not contain the JNI_CreateJavaVM symbol

问题描述

我需要通过JDK 1.7在Mac OS上运行Eclipse Kepler(这是PyDev插件所必需的).

I need to run Eclipse Kepler on Mac OS through a JDK 1.7 (This is required by the PyDev plugin).

问题是，尽管我已经成功安装了1.7 jdk并配置了eclipse.ini以使用它，但还是收到了错误消息

The problem is that although I have managed to install the 1.7 jdk and configured the eclipse.ini to use it I get the error

JVM共享库"/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/bin../jre/lib/server/libjvm.dylib"不包含JNI_CreateJavaVM符号.

The JVM shared library "/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/bin../jre/lib/server/libjvm.dylib" does not contain the JNI_CreateJavaVM symbol.

更新 这里的聪明人 https://github.com/joeferner/node-java/issues/90 声称足以将JNI添加到info.plist文件中的JVMCapabilities中，例如

UPDATE smart people here https://github.com/joeferner/node-java/issues/90 claim it is enough to add JNI to the JVMCapabilities in the info.plist file like

<key>JVMCapabilities</key>
   <string>JNI</string>

但是我尝试过，但在我的情况下不起作用

But I tried it and it does not work in my case

推荐答案

右键单击Eclipse图标，然后选择显示软件包内容".在目录目录中，您将找到一个名为"Info.plist"的文件.向下滚动到文件底部，直到找到

Right click on the Eclipse icon and select 'show package contents'. Inside the contents directory you'll find a file called 'Info.plist'. Scroll down to the bottom of the file till you find this

<key>Eclipse</key>
    <array>
        <!-- to use a specific Java version (instead of the platform's default) uncomment one of the following options,
                or add a VM found via $/usr/libexec/java_home -V
          <string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java</string>
          <string>-vm</string><string>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Commands/java</string>
        -->

请注意已注释掉的部分.将jdk路径声明移出注释部分.现在应该看起来像这样.

Notice the commented out section. Move the jdk path declaration out of the comments section. It should look like this now.

<key>Eclipse</key>
    <array>
      <string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java</string>
        <!-- to use a specific Java version (instead of the platform's default) uncomment one of the following options,
                or add a VM found via $/usr/libexec/java_home -V
          <string>-vm</string><string>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Commands/java</string>
        -->

最后一步，浏览至/Library/Java/JavaVirtualMachines并检查其中存在的jdk软件包名称.替换上面命令中的jdk版本.

Last step, browse to /Library/Java/JavaVirtualMachines and check the jdk package name present there. Replace the jdk version in the above command with that.

/Library/Java/JavaVirtualMachines/{your_jdk_package_name}/Contents/Home/bin/java

可选:完成某些步骤后，在某些机器上，您可能必须关闭取景器，导航至eclipse文件夹，然后再次单击eclipse使其起作用.

Optional: On some machines you may have to close the finder after you've done all this, navigate to the eclipse folder and click on eclipse again for it to work.
