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。JavaFX 工具因此被禁用。将 Java7/8 设为默认系统 java 或调整 eclipse.ini 以传递 -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常规 > 启动和关闭并取消选中“JavaFX 工具 Java 检查”

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信息。我也尝试修改我的eclipse.ini：

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

这给了我另一个错误消息：

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

所以我回到原来的状态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，错误日志如下：

有什么线索吗？提前谢谢！

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。Eclipse Kepler 的升级解决了这个问题。
