java 在自己的maven插件中使用lambda“破坏”安装插件目标

我开始创建我自己的maven插件，一切都很好，并与documentation from maven一起工作。
现在我创建了一个新的类，我想在其中排序列表：
公共类版本解析器{

File file;

public VersionResolver(String path) {

    ...
}

public List<String> getAvailableOrderedVersions(){

    File[] versionFolders = file.listFiles(new FilenameFilter() {
        public boolean accept(File dir, String name) {
            return name.startsWith("v");
        }
    });

    List<String> versions = new ArrayList<String>();
    for (File f :versionFolders) {
        if (f.isDirectory()){
            versions.add(f.getName().replace("v", ""));
        }
    }

    Comparator<String> comparator = new Comparator<String>() {

        public int compare(String v1, String v2) {
               .....(code not really relevant)...
        }
    };

    Collections.sort(versions, comparator);

    return versions;
}

由于有了Lamda，这可以像这样完成：

versions.sort((v1, v2) -> {

        ....
    });

之后，当我安装mvn时，我得到错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (default-descriptor) on project lsg-installer-maven-plugin: Execution default-descriptor of goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor failed: 52264 -> [Help 1]

我的父母pom有：

<build>
    <pluginManagement>
        <plugins>
            <plugin>

                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

maven插件pom如下所示：

            </plugin>
        </plugins>
    </build>
</project>

有人知道我哪里做错了吗？
编辑：
这是mvn -x安装的输出

要在我的maven插件中使用lamdas，我必须在最近的版本（在我的情况下是3.5）中使用maven-plugin-plugin，如下所示：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-plugin-plugin</artifactId>
    <version>3.5</version>
</plugin>
