无法使用Maven编译简单的Java 10 / Java 11项目

Question

我有一个琐碎的Maven项目：

src
└── main
    └── java
        └── module-info.java
pom.xml
pom.xml：

<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>example</name>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <release>10</release>
            </configuration>
        </plugin>
    </plugins>
</build>

当我通过构建项目时mvn -X install -DskipTests=true，它失败了：

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile (default-testCompile) on project example: Execution default-testCompile of goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile failed.

有没有办法来解决这个问题？

可以将maven中使用的java版本配置为JDK / 11以下的任何版本，并使用maven-compiler-plugin:3.8.0来指定9,10,11的发行版而没有任何明确的依赖关系。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>11</release>  <!--or <release>10</release>-->
    </configuration>
</plugin>
