Question

我在OS X Mountain Lion上安装了e（fx）clipse插件。当我启动eclipse时，我收到以下错误消息：

您没有使用Java7或Java8运行eclipse实例。因此，JavaFX工具被禁用。使Java7 / 8成为默认的系统java或调整你的eclipse.ini 传递-vm指向您的Java7 / 8安装。如果您想关闭此检查，请打开您的首选项并转到General＆gt;启动和关闭并取消选中 'JavaFX Tooling Java Check'

所以我检查了JAVA_HOME并将以下行添加到我的.profile：

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home

我的java现在是：

Kinnlas-MacBook:libexec kinnla$ java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

但仍然有相同的错误消息。我还尝试修改我的eclipse.ini：

-vm
/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java

这给了我另一条错误消息：

JVM共享库“/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk” 不包含JNI_CreateJavaVM符号。

所以我回到原来的eclipse.ini并尝试从shell启动eclipse：

java -jar /Applications/eclipse/plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar

启动失败，出现以下错误日志：

任何线索？ Thx提前！

问题可能是os-x jdk 1.7.0_25-b15，eclipse Juno和e（fx）clipse插件之间不兼容。升级到日食开普勒解决了这个问题。

OS X上的JAVA_HOME和e（fx）剪辑
