我在 S3 中有一个私有(private)存储库，我用它来发布一个库，然后我在另一个项目中使用它。
要发布，我有这个设置:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
<extensions>
<extension>
<groupId>com.allogy.maven.wagon</groupId>
<artifactId>maven-s3-wagon</artifactId>
<version>1.1.0</version>
</extension>
</extensions>
</build>
<distributionManagement>
<repository>
<id>projectx-aws-release</id>
<name>ProjectX AWS Release Repository</name>
<url>s3://projectx-support/maven2</url>
</repository>
<snapshotRepository>
<id>projectx-aws-snapshots</id>
<name>Projectx AWS Snapshot Repository</name>
<url>s3://projectx-support/maven2</url>
</snapshotRepository>
</distributionManagement>
然后，在使用该库的应用程序上:
<build>
...
<extensions>
<extension>
<groupId>com.allogy.maven.wagon</groupId>
<artifactId>maven-s3-wagon</artifactId>
<version>1.1.0</version>
</extension>
</extensions>
</build>
<repositories>
<repository>
<id>projectX-aws</id>
<url>s3://projectX-support/maven2</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
.circleci/settings.xml 具有 S3 存储库的凭据:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<servers>
<server>
<id>projectx-aws</id>
<username>....</username>
<password>....</password>
</server>
</servers>
</settings>
运行 mvn --batch-mode --settings .circleci/settings.xml dependency:go-offline 时会发生一些奇怪的事情。它会快速下载一些依赖项:
mvn --batch-mode --settings .circleci/settings.xml dependency:go-offline

有什么想法吗？这似乎是不确定的。它伴随着不应该对其产生任何影响的变化来来去去，尽管它似乎非常一致，因为重建似乎并没有改变结果。我确信凭据有效，因为它们在两个项目中使用，一个正在运行，并且它们与该项目在运行时使用的相同。
自从我从 Gradle 切换到 Maven 后，这种情况一直在发生，但由于这是一个完全不同的系统，我认为这不是一个非常有用的比较。
当我在自己的计算机上运行 mvn --batch-mode --settings .circleci/settings.xml dependency:go-offline install -e -X 时，删除 ~/.m2/存储库，输出如下所示:https://gist.github.com/pupeno/da4f53a6e9673ff611909021306191a4#file-maven-local-machine-log当我在 CircleCI 中做同样的事情时，它看起来像这样:https://gist.github.com/pupeno/da4f53a6e9673ff611909021306191a4#file-maven-circleci-log

最佳答案
可能主要问题是对 Amazon S3 存储库的请求过多。
通过分析日志，我们可以看到在短短 1-3 秒内从 Amazon S3 下载文件的请求超过 120 个:
- Maven 正在下载
Amazon S3中不存在的 Artifact ，然后 从Maven Central下载它，那些对Amazon S3的请求是无用的 - 每次下载都需要登录和注销请求，这很奇怪!
- 最后 40 个请求被拒绝连接
- 最后 40 个请求没有 [INFO] 登录 - projectx-support 为他们声明，所以可能在短时间内登录有一些限制？
要解决这个问题，至少有2个方案:
强制 Maven 从
Maven Central下载 artefact FIRSTLY， 然后从Amazon S3休息，以减少对Amazon S3的请求。 这是一个很好的解决方案，但请记住，如果您还有更多 仅从Amazon S3下载的人工制品你会得到相同的 问题!默认
Maven Central在存储库中排在最后，要设置最高优先级并首先从Maven Center下载，我们必须 将其手动添加到我们存储库中的FIRST 位置，因为存储库的顺序也将决定存储库访问的顺序。 ( Source ):<repositories> <repository> <id>central</id> <name>Central Repository</name> <url>https://repo.maven.apache.org/maven2</url> <layout>default</layout> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>projectX-aws</id> <url>s3://projectX-support/maven2</url> <releases><enabled>true</enabled></releases> <snapshots><enabled>true</enabled></snapshots> </repository> </repositories>- 找到一种方法来更改
Amazon S3上 IP 的请求限制 存储库。此解决方案将始终有效，但您的 Amazon S3 会收到许多无用的请求。
所以解决问题的最佳方法是混合使用这两种解决方案。 :)
关于java - Maven 正在尝试从私有(private)存储库安装每个 jar，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49744633/
