私は私のポンポンファイルで以下のようにMaven-コンパイラプラグインを追加しました：

<properties>
    <java.version>11</java.version>
    <maven.compiler.source>${java.version}</maven.compiler.source>
    <maven.compiler.target>${java.version}</maven.compiler.target>
    <maven.compiler.release>${java.version}</maven.compiler.release>
 </properties>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>${java.version}</release>
        <source>${java.version}</source>
        <target>${java.version}</target>
    </configuration>
</plugin>

私は何か間違ってやっているなら、私を案内してください。
