Question

我使用的是Xubuntu，我还没有root或sudo帐户。

我也在审查这个问题

java.lang.UnsupportedClassVersionError: org/sonar/batch/bootstrapper/EnvironmentInformation : Unsupported major.minor version 52.0

How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version

但是，我在计算机上做更改的选项较少（我没有安装，我无法安装其他netbeans或Java）。

我想在空闲时间使用netbeans。我有Java，但我无法改变我的环境。

$ update-alternatives --config java
Existen 4 opciones para la alternativa java (que provee /usr/bin/java).

现在回顾javac

$ update-alternatives --config javac
Existen 4 opciones para la alternativa javac (que provee /usr/bin/javac).

我是从（How to set JAVA_HOME in Linux for all users）执行此操作的：

$ /usr/bin/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)
$

$ export JAVA_HOME=/opt/jdk/jdk1.8.0_111
$ export PATH=/opt/jdk/jdk1.8.0_111:$PATH

我正在尝试：

$ export JAVA_HOME=/opt/jdk/jdk1.7.0_79
$ export PATH=/opt/jdk/jdk1.7.0_79:$PATH

但结果是一样的！

$ ls -al

drwxr-xr-x 24 someone domain users    4096 ene  9 10:18 ..

-rw-r--r--  1 someone domain users  657903 sep 30  2016 netbeans.exe
$

我有同样的问题!!!

是否可以在这些条件下使用netbeans而不安装它？怎么样？

我使用CentOS 7在家里使用netbeans Independent，效果很好。

Netbeans 8.2（操作系统独立ZIP），不支持的major.minor版本52.0，非sudo，root
