Answer 1

我也遇到了同样的问题，在我把11版改成1.8版后，它也适用于我。

替换

<properties>
   <java.version>11</java.version>
  </properties>

使用

<properties>
   <java.version>1.8</java.version>
  </properties>

Answer 2

由于你没有粘贴完整的错误，我相信你可能会得到下面的错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project demo: Fatal error compiling: error: invalid target release: 1.11 -

对于maven编译器，正确的JDK版本为1.8、1.9、1.10、11、12。

您也可以简单地将上面的<properties>标记替换为下面的

    <properties>
    <java.version>11</java.version>
   </properties>

我从Spring Initializr的一个示例项目中获取了上面的代码。你也可以从maven编译器插件中删除配置。

Answer 3

您可以将maven.compiler.target版本从1.11更改为11

<properties>
    <maven.compiler.source>11</maven.compiler.source>
    <maven.compiler.target>11</maven.compiler.target>
    <maven.compiler.release>11</maven.compiler.release>
</properties>
