NetBeans 8.1 Activation Failure
提问by kylas
I am trying to install NetBeans 8.1 on my Ubuntu 14.04.3 LTS. When I try to create a new project, it shows an error, saying that "not all requested modules can be enabled". I tried activating it from the plugins, but to no avail.
我正在尝试在我的 Ubuntu 14.04.3 LTS 上安装 NetBeans 8.1。当我尝试创建一个新项目时，它显示一个错误，说“并非所有请求的模块都可以启用”。我尝试从插件激活它，但无济于事。
Why is this happening, and what can I do to resolve it?
为什么会发生这种情况，我可以做些什么来解决它？

I had the same problem with NetBeans 8.1 on Linux Mint 17.2 and I found the solution (during install a have chosen wrong JDK directory).
我在 Linux Mint 17.2 上的 NetBeans 8.1 遇到了同样的问题，我找到了解决方案（在安装过程中选择了错误的 JDK 目录）。
If a compatible JDK installation cannot be found, you might need to manually add a path to the JDK installation directory by doing the following:
如果找不到兼容的 JDK 安装，您可能需要通过执行以下操作手动添加到 JDK 安装目录的路径：
- Open the netbeans.conffile located in the netbeans/etcdirectory in a text editor.
- Enter the location of a compatible JDK installation for the netbeans_jdkhome option. The default location in Windows is C:\Program Files\Java\jdk1.7.0_67 or similar.
In my case: /usr/lib/jvm/java-8-oracle/ - Save the netbeans.conf file and run the executable file in the netbeans/bin directory.
- 在文本编辑器中打开位于netbeans/etc目录中的netbeans.conf文件。
- 为 netbeans_jdkhome 选项输入兼容的 JDK 安装位置。Windows 中的默认位置是 C:\Program Files\Java\jdk1.7.0_67 或类似位置。
就我而言：/usr/lib/jvm/java-8-oracle/ - 保存 netbeans.conf 文件并运行 netbeans/bin 目录中的可执行文件。

Just in case, I solved this just by commenting out the following line;
以防万一，我只是通过注释掉以下行来解决这个问题；
netbeans_jdkhome="/usr"
To
到
#netbeans_jdkhome="/usr"
Edit:
编辑：
The directory of the above code is inside the file ~/netbeans-8.1/etc/netbeans
上面代码的目录在文件~/netbeans-8.1/etc/netbeans里面

Make sure that right JDK directory chosen in the installation wizard if you not sure you can change it from C:\Program Files\NetBeans {netbeans version}\etcyou will see a file which is netbeans.confedit it(I am using Notepad++ for that) At the bottom of the file, you will see a line netbeans_jdkhome="C:\Program Files\Java\{jdk directory you want}"make sure it is valid JDK and it is JDK, not JRE
确保在安装向导中选择了正确的 JDK 目录，如果您不确定可以更改它，C:\Program Files\NetBeans {netbeans version}\etc您将看到一个正在netbeans.conf编辑它的文件（我正在使用 Notepad++）在文件的底部，您将看到一行netbeans_jdkhome="C:\Program Files\Java\{jdk directory you want}"make确定它是有效的 JDK 并且它是 JDK，而不是 JRE
