我開始創建自己的Maven插件。一切都很好，并且使用了maven的文檔。現在，我創建了一個新類，在其中我要對列表進行排序：公共類VersionResolver {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;}多虧了lamda，它可以像這樣完成：    versions.sort((v1, v2) -> {        ....    });之后，當我執行mvn安裝時，出現錯誤消息：[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][ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException我的父母pom有：<build>    <pluginManagement>        <plugins>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <configuration>                    <source>1.8</source>                    <target>1.8</target>                </configuration>            </plugin>        </plugins>    </pluginManagement></build>
