英文:
Java 11 : Error:java: invalid source release: 11 - Not sure what to do anymore
问题
你好，我已经为你完成了翻译：
你好，我已经从Java 8升级到了Java 11，无论如何都会遇到以下错误。我正在使用IntelliJ和Windows 10。
我对11所做的更改如下：
-
在项目结构 -> 项目中：
-
项目结构 -> 模块
- 我的编译器模块目标字节码版本在设置 -> 构建、执行、部署 -> Java编译器中也设置为了11。
我甚至将环境变量JAVA_HOME分别更改为用户变量和系统变量中的jdk-11.0.8。
当我运行java -version和javac -version时，两者都显示我安装了版本11。
当我尝试运行mvn clean package时，总是失败并显示以下错误
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project abc: Fatal error compiling: invalid target release: 11 -> [Help 1]
请帮我解决这个错误，非常感谢您的帮助！
附加说明 这是项目的pom的一部分
<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>

<encoding>UTF-8</encoding>
<showWarnings>true</showWarnings>
<showDeprecation>true</showDeprecation>

<parameters/>
</compilerArguments>
</configuration>
我还添加了<release>11</release> <!--或 <release>10</release>-->，但问题仍然存在。
英文:

What i have changed to 11:
1)In Project Structure -> Project:
2)Project Structure ->Modules
3)My compiler module Target bytecode version is set to 11 aswell in settings->Build,Execution,Deployment -> Java Compiler.
I even changed Both environment variables respectiveley the JAVA_HOME in user variables and JAVA_HOME in system variables to jdk-11.0.8.
When i run java -version and javac -version both show that i have version 11 installed.
When i try running a mvn clean package it always fails with this error
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project abc: Fatal error compiling: invalid

请在IntelliJ中检查您的JDK 11设置！尽管项目SDK被称为11，但它仍然显示您的java版本为1.8.161。从这个信息来看，似乎您的新JDK 11仍然指向您的旧1.8安装，而旧版本不支持版本11。
英文:
Please check your JDK 11 Setup in IntelliJ! Even though the project SDK is called 11, it still says that your java-version is 1.8.161. Judging from this it looks like your new jdk 11 still points to your old 1.8 installation which does not now about version 11 yet.

对我来说，解决方法是设置JAVA_HOME变量。尽管你提到过它作为你尝试过的解决方案，但很容易忽略它。我正在处理不同的项目，并且在一些项目中使用java 8，在另一些项目中使用java 11。我不得不在这些版本之间切换以使其正常工作。
英文:
For me the solution was setting the JAVA_HOME var. Though you mentioned it as a solution you tried it's easy to read over it. I'm working with different projects and using java 8 for a few and java 11 for another. I had to switch between these versions to get this to work
