In your pom.xmlfile, simply remove the tag <release>8</release>from your maven-compiler-pluginconfiguration:
在您的pom.xml文件中，只需<release>8</release>从您的maven-compiler-plugin配置中删除标签 ：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<verbose>true</verbose>
</configuration>
</plugin>

This configuration worked for me, for java 11. (IntelliJ version 2019.1) java.version is 11, declared in the properties part of the pom.xml. Maven version should be 3.6 or higher.
此配置对我有用，适用于 java 11。（IntelliJ 版本 2019.1）java.version 为 11，在 pom.xml 的属性部分中声明。Maven 版本应该是 3.6 或更高。

This has to do with the version of JDK running on your system. As per the documentation for maven-compiler-plugin, the release flag is supported since 1.9, and thus has to be commented/removed from the POM if you are using prior (1.8 and below) versions of JDK.
这与系统上运行的 JDK 版本有关。根据 maven-compiler-plugin 的文档，从 1.9 开始支持 release 标志，因此如果您使用以前（1.8 及以下）版本的 JDK，则必须从 POM 中注释/删除。
Check Maven documentation for release tag for maven-compiler-plugin here
在此处检查 Maven 文档以获取 maven-compiler-plugin 的发布标记
