我对Maven Javadoc插件和自定义doclet有问题。
我使用的是maven javadoc插件v22.10.1和一个自定义doclet，它基本上是一个maven jar项目。
我还有一个settings.xml，它将central存储库定义为自定义的artifactory。
问题是，每当我运行maven javadoc插件时，它都会试图从https://repo.maven.apache.org/maven2中解析自定义doclet的依赖项，也就是它从自定义artifactory中解析的doclet本身
调试输出也很奇怪，它说central存储库是https://repo.maven.apache.org/maven2，而snapshot存储库是我的自定义快照artifactory
它就像maven jar插件覆盖settings.xml的central存储库一样锁定。
如何告诉maven-jar-plugin不要覆盖我的central存储库。
调试日志如下所示：

关于
可能的故障排除路径：
Maven设置(在您的最新更新/编辑后，已经检查过了)
为自定义Maven存储库提供配置的settings.xml文件可能只指向它的repositories部分(用于依赖关系中介的存储库)，而不指向pluginRepositories部分(用于插件/报告中介和插件的依赖关系中介)。
根据官方maven文件，pluginRepositories应规定：
用于发现插件的远程存储库的列表。
如果没有这个额外的配置，Maven将尝试解决插件对插件默认存储库的依赖，该存储库来自Maven超级POM。从外观上看，插件的默认存储库实际上就是您的构建所指向的存储库(https://repo.maven.apache.org/maven2)：

如果您想查看Maven构建使用的有效设置，那么您可以运行以下命令并检查其输出：
mvn help:effective-pom
effective-pom目标将打印整个合并的pom和所使用的设置，作为构建输出的一部分。从中，您应该能够看到哪个pluginRepositories是您的构建有效使用的。
注意：-Doutput参数可能有助于将其重定向到外部文件。
人工配置
如果不是这样(因此，配置是一致的，并且在两个部分都指向您的自定义Maven存储库)，您应该检查自定义存储库是否配置良好：
- Artifactory带有库、插件和快照的默认存储库
- Artifactory可以配置为使用虚拟存储库，在后面聚合几个真实的存储库
- 您的自定义库可能已上载到lib存储库，而该库不包含在提供插件依赖关系的虚拟存储库中
来自您提供的输出片段：
[DEBUG] Repositories (dependencies): [central (PATH TO CUSTOM LIBS RELEASE REPOSITORY, default, releases), snapshots (PATH TO CUSTOM LIBS SNAPSHOT REPOSITORY, default, releases+snapshots)]
[DEBUG] Repositories (plugins) : [central (PATH TO CUSTOM PLUGIN RELEASE REPOSITORY, default, releases), snapshots (PATH TO CUSTOM PLUGIN SNAPSHOT REPOSITORY, default, releases+snapshots)]
事实可能就是这样。
这是一个常见的错误配置(我过去也遇到过这种情况)。事实上，在大多数情况下，你甚至不需要一个不同的插件依赖性存储库，而且只有一个发布库和一个快照库的虚拟存储库会更容易、更清楚，这两个存储库都提供依赖性和插件工件。因此，只区分已发布和快照，而不区分依赖项和插件(或者，如果你真的想保持当前配置，你可以添加libs存储库作为虚拟插件存储库的一部分)。
一个简单无害的测试是：
- 在Artifactory中配置一个新的虚拟存储库
- 新的虚拟存储库将包括库和插件存储库
- 在Maven设置中配置新的虚拟存储库(在两个存储库部分)
- 再次运行Maven构建
使用插件依赖项(在您的最新评论之后：宾果！，这解决了问题)
您应该将所需的依赖项添加为插件依赖项，如下所示：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.1</version>
<configuration>
<show>public</show>
<excludePackageNames>*.ws.jaxws.*</excludePackageNames>
<additionalparam>-Xdoclint:none</additionalparam>
</configuration>
<executions>
<execution>
<id>default-cli</id>
<goals>
<goal>javadoc</goal>
</goals>
<configuration>
<docletArtifacts>
<docletArtifact>
<groupId>GROUP ID OF CUSTOM DOCLET</groupId>
<artifactId>ARTIFACT ID OF CUSTOM DOCLET</artifactId>
<version>VERSION OF CUSTOM DOCLET</version>
</docletArtifact>
</docletArtifacts>
<doclet>PACKAGE AND CLASS OF CUSTOM DOCLET</doclet>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>GROUP ID OF CUSTOM DOCLET</groupId>
<artifactId>ARTIFACT ID OF CUSTOM DOCLET</artifactId>
<version>VERSION OF CUSTOM DOCLET</version>
</dependency>
</dependencies>
</plugin>
请注意相关plugin部分底部的dependencies部分。插件不解析项目依赖项，因此如果需要外部库，则需要将它们声明为插件依赖项。
然而，Javadoc Maven插件还提供了一个additionalDependencies，它为其特定范围复制了上面的(标准)功能。
向javadoc类路径添加可选依赖项的能力
然而，根据您的反馈，标准方法成功了。
EDIT(02/02/2016 9:37)
如果您还需要报告依赖项(根据您的最新评论)，那么报告部分实际上并没有像插件那样预见插件依赖项。这是已知的问题。
然而，建议使用两种解决方案：
将依赖项设置为build[extension](https://maven.apache.org/pom.html#Extensions)(见下面的片段)，尽管不推荐
<build> <extensions> <extension> <groupId>GROUP ID OF CUSTOM DOCLET</groupId> <artifactId>ARTIFACT ID OF CUSTOM DOCLET</artifactId> <version>VERSION OF CUSTOM DOCLET</version> </extension> </extensions> </build>根据官方文件：
Extensions是要在此构建中使用的工件列表。它们将包含在正在运行的构建的类路径中。
设置插件的依赖关系(如上所述)应该同时应用于插件和报告机制，如本Sonatetype post 中所述
有一种方法可以通过报告实现这一点。在下面的例子中，我从插件块中删除了执行，并将插件添加为报告。在报告中使用插件时，依赖关系似乎是继承的。
这里也记录了类似的方法。
编辑(2016年2月3日)(在您的最新评论之后：宾果！，使用构建扩展修复了问题)
使用docletPath配置元素
查看Maven Javadoc插件的官方文档，docletPath配置元素应该提供外部文件的路径(依赖项)，该路径与官方javadoc命令的预期docletPath选项一致。
从官方文档来看，路径方法比Maven依赖方法更受欢迎。因此，您的配置可以调整如下：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.1</version>
<configuration>
<show>public</show>
<excludePackageNames>*.ws.jaxws.*</excludePackageNames>
<additionalparam>-Xdoclint:none</additionalparam>
</configuration>
<executions>
<execution>
<id>default-cli</id>
<goals>
<goal>javadoc</goal>
</goals>
<configuration>
<docletArtifacts>
<docletArtifact>
<groupId>GROUP ID OF CUSTOM DOCLET</groupId>
<artifactId>ARTIFACT ID OF CUSTOM DOCLET</artifactId>
<version>VERSION OF CUSTOM DOCLET</version>
</docletArtifact>
</docletArtifacts>
<doclet>PACKAGE AND CLASS OF CUSTOM DOCLET</doclet>
<docletPath>path_to_jar/fileName.jar</docletPath>
</configuration>
</execution>
</executions>
</plugin>
注意docletPath元素，一个用于所有docletArtifacts。根据文件：
指定doclet起始类文件(使用-doclet选项指定)及其所依赖的任何jar文件的路径。docletPath可以包含多个路径，方法是用冒号(：)或分号(；)分隔。
一个官方示例还展示了如何使用它：我尝试了它，在我们的内部公司Artifactory上配置了依赖项，并且没有指定任何jar的路径，并且成功地解决了额外的依赖项，因此，我还会再次检查Artifactory的配置，以及您的自定义doclet库是否可以从插件库访问。
