If you are using Ubuntu, you could do the following, too:
如果您使用的是 Ubuntu，您也可以执行以下操作：
sudo update-alternatives --config javac
That worked for me.
那对我有用。
For more information about installing java/javac using update-alternatives, please refer to: How do I make java default to a manually installed JRE/JDK?

So I found that Ionic at the time of post-Cordova does not like JDK above 1.8.
所以我发现后Cordova的时候的Ionic不喜欢1.8以上的JDK。
- To Solve get JDK 8.
- Remove any JDK or JRE version higher than version 8 because it will automatically look for the highest version JDK the Java folder in c drive.
- 解决得到JDK 8。
- 删除任何高于版本 8 的 JDK 或 JRE 版本，因为它会自动在 c 驱动器中的 Java 文件夹中查找最高版本的 JDK。
OR
或者
- Next solution is to just change what JDK Cordova looks for to version 8.
- 下一个解决方案是将 JDK Cordova 查找的内容更改为版本 8。

This is my best option for my case, I use Cordova 6.2 version (not latest). I've worked with 1.7 Java as long as I can follow the technology from them. But since Cordova upgrade their system, now they prepare using 1.8 to implemented. If I not wrong, since 6.3 version their using that. I work in Snow Leopard with 1.7 java, it's hard to move on to upgrade my OS since I use old Macbook, I don't have several choice here.
这是我的最佳选择，我使用 Cordova 6.2 版本（不是最新的）。只要我能遵循他们的技术，我就一直在使用 1.7 Java。但是自从 Cordova 升级他们的系统后，现在他们准备使用 1.8 来实现。如果我没记错的话，他们从 6.3 版本开始使用那个。我在 Snow Leopard 使用 1.7 java 工作，因为我使用旧的 Macbook，所以很难继续升级我的操作系统，我在这里没有几个选择。
