您的错误说

致命错误编译：错误：无效的目标版本：13.0.1

[您正在使用maven-compiler-plugin 3.0，但是至少需要3.8才能使用Java13。这可以通过<plugin>标记完成，尽管您可能应该考虑将Maven更新为3.5：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <source>13</source>
        <target>13</target>
    </configuration>
</plugin>

[查看this article，了解使用Java 13还需要其他什么。
