maven - 如何让 Maven 运行从 3rd 方存储库下载的插件

问题描述

使用 Maven 3.8.2

我有一个从自定义 Maven 存储库下载的插件：

$ mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:get \
-DremoteRepositories=excelfore.private::::https://some_url \
-Dartifact=com.excelfore:appshack-maven-plugin:4.2133-RC1:maven-plugin
...
[INFO] BUILD SUCCESS

现在我只想运行插件：

$ mvn -e com.excelfore:appshack-maven-plugin:4.2133-RC1:run-self-test

结果是：

[错误] 插件 com.excelfore:appshack-maven-plugin:4.2133-RC1 或其依赖项之一无法解析：未能在https://中找到 com.excelfore:appshack-maven-plugin:jar:4.2133-RC1 repo.maven.apache.org/maven2被缓存在本地仓库，直到中央的更新间隔已经过去或强制更新才会重新尝试解析 -> [帮助1]

我如何告诉 Maven 只使用它之前下载的文件？

我试过-o了，这只是更改为：

[错误] 插件 com.excelfore:appshack-maven-plugin:4.2133-RC1 或其依赖项之一无法解决：无法在离线模式下访问中央 ( https://repo.maven.apache.org/maven2 ) 和artifact com.excelfore:appshack-maven-plugin:jar:4.2133-RC1 之前没有下载过。-> [帮助 1]

-npu似乎没有做任何事情，它显示有关此选项已弃用的警告，并且错误是相同的。

使用-X我可以看到这些消息：

[DEBUG] Using local repository at /home/vps/.m2/repository
[DEBUG] Using manager EnhancedLocalRepositoryManager with priority 10.0 for /home/vps/.m2/repository
[INFO] Scanning for projects...
[DEBUG] Extension realms for project org.apache.maven:standalone-pom:pom:1: (none)
[DEBUG] Looking up lifecycle mappings for packaging pom from ClassRealm[plexus.core, parent: null]

当然所有文件都在那里，我什至验证了 SHA1 总和匹配：

[vps@hornet]~$ ll ~/.m2/repository/com/excelfore/appshack-maven-plugin/4.2133-RC1/
-rw-rw-r--. 1 vps 317291 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.jar
-rw-rw-r--. 1 vps    341 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.jar.lastUpdated
-rw-rw-r--. 1 vps     40 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.jar.sha1
-rw-rw-r--. 1 vps   3248 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.pom
-rw-rw-r--. 1 vps    341 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.pom.lastUpdated
-rw-rw-r--. 1 vps     40 Aug 19 12:43 appshack-maven-plugin-4.2133-RC1.pom.sha1
-rw-rw-r--. 1 vps    252 Aug 19 12:43 _remote.repositories

似乎我错过了一些愚蠢的东西，似乎有时这工作得很好，但我经常碰到这堵砖墙。我希望 Maven 不会尝试同步已成功下载的工件。

我认为问题是 Maven 在运行插件时不知道私有存储库，但我需要在任何项目之外运行它（即没有 POM 文件），并且 AFAIU，无法在~/.m2/settings.xml（只有服务器，这无济于事）。

然而，更奇怪的是，这适用于快照。

$ mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:get \
 -DremoteRepositories=excelfore.private::::https://some_url \
 -Dartifact=com.excelfore:appshack-maven-plugin:4.2132-SNAPSHOT:maven-plugin
...

从调试输出来看，它不会对快照进行这种“可用性验证”。但是，使用-U标志绝对没有区别。
