我已经搜索了许多OpenSUSE论坛以获得答案,但到目前为止我还没有找到答案.简而言之,从Oracle安装JDK的RPM时,我会收到以下信息：

请原谅我的高度冗长,我只是想让你看到我所看到的.这是一个全新安装的OpenSUSE Tumbleweed.

我也尝试在OpenSUSE Leap 42.2上安装它,并进行全新安装.在我第一次尝试之后,我重新加载了没有任何Java支持(没有OpenJDK)从头开始,因为我已经完成了这个安装.我已经按照指南在OpenSUSE上专门安装了Java.没有安装Java的那些,之前安装了java OpenJDK的那些,无论出于何种原因安装JDK和JRE的那些,等等.

为了记录,Java本身正在运行,但显然控制面板不是.我尝试手动使用update-alternatives,我试图从头开始编译,我已经重新加载,我已经从Leap切换到Tumbleweed.以下是一些可能有用的其他信息：

> sudo update-alternatives --list java
/usr/java/jdk1.8.0_111/jre/bin/java
> sudo update-alternatives --config java
There is only one alternative in link group java (providing /usr/bin/java): /usr/java/jdk1.8.0_111/jre/bin/java
Nothing to configure.
> java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
> javac -version
javac 1.8.0_111

再一次,我可以看到Java正在运行.但是我仍然想知道为什么这么容易重现以及如何修复它.

解决方法:

执行此安装的过程比大多数人认为更容易,并且令人惊讶的是,关于如何执行此操作没有太多好的或直接的信息.上面的答案是正确的,但有一些元素有点过时.
