In my specific case, I remove and reinstall all java packages and add one (for 'instinct'):
I removed:java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-plugin
在我的特定情况下，我删除并重新安装所有 java 包并添加一个（对于“本能”）：
我删除了：java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-plugin
And added:java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-pluginjava-1_8_0-openjdk-devel<<-- luckily I hit it
并补充说：java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-pluginjava-1_8_0-openjdk-devel<<--幸运的是我击中了它
The bin inside main folder appears. With javac and another things.
Thank you guys!
出现主文件夹内的 bin。用 javac 和别的东西。
感谢你们！

Cordova needs a JDKnot a JRE, since it is checking for javac. See check_reqs.jsline 86. From your comments you are saying that "Inside this path, there isn't the bin folder" in a JDKyou should have a bindirectory!
Cordova 需要一个JDKnot a JRE，因为它正在检查javac. 请参阅check_reqs.js行86。根据您的评论，您是说“在此路径中，没有 bin 文件夹”，JDK您应该有一个bin目录！
回答by Bilal Shah
Your path should be like this
你的路径应该是这样的
PATH=$PATH:$ANDROID_HOME/bin:$JAVA_HOME/bin
PATH=$PATH:$ANDROID_HOME/bin:$JAVA_HOME/bin
and than
export PATH
然后
export PATH

It's a bit of misunderstanding with java-X_X_X-openjdk packages. Especially when you are used to default Oracle notation.
对 java-X_X_X-openjdk 包有点误解。特别是当您习惯于默认 Oracle 表示法时。
The JDK part is confusing, because OpenJDK is a project of an open-source implementation of the Java Platformand not a JDK - package actually allowing you to develop in Java. (more precise info here: http://openjdk.java.net/install/index.html)
JDK 部分令人困惑，因为OpenJDK 是 Java 平台的开源实现项目，而不是 JDK - 实际上允许您使用 Java 进行开发的包。（这里有更准确的信息：http: //openjdk.java.net/install/index.html）
TLDR:
域名注册地址：
java-X_X_X-openjdk is Oracle's JRE equivalent.
java-X_X_X-openjdk-devel is Oracle's JDK equivalent.
java-X_X_X-openjdk 是 Oracle 的 JRE 等价物。
java-X_X_X-openjdk-devel 是 Oracle 的 JDK 等价物。

To build and run apps, you need to install SDKs for each platform you wish to target. Alternatively, if you are using browser for development you can use browser platform which does not require any platform SDKs.
要构建和运行应用程序，您需要为要定位的每个平台安装 SDK。或者，如果您使用浏览器进行开发，则可以使用不需要任何平台 SDK 的浏览器平台。
To check if you satisfy requirements for building the platform:
要检查您是否满足构建平台的要求：
$ cordova requirements
Requirements check results for android:
Java JDK: installed .
Android SDK: installed
Android target: installed android-19,android-21,android-22,android-23,Google Inc.:Google APIs:19,Google Inc.:Google APIs (x86 System Image):19,Google Inc.:Google APIs:23
Gradle: installed
Requirements check results for ios:
Apple OS X: not installed
Cordova tooling for iOS requires Apple OS X
Error: Some of requirements check failed
