那些遇到过的问题

Maven正试图从私有存储库安装每个jar

pup*_*eno 16 java amazon-s3 maven

我在S3中有一个私有存储库,用于发布一个库,然后我在另一个项目中使用.

要发布,我有这个设置:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>

然后,在使用该库的应用程序上:

当运行mvn --batch-mode --settings .circleci/settings.xml dependency:go-offline奇怪的事情时.它会快速下载一些依赖项:

Any ideas what's going on? This seems to be non-deterministic. It comes and goes with changes that shouldn't have any effect on it, although it seems to be quite consistent in that re-building doesn't seem to change the outcome. I'm sure the credentials work because they are used in two projects and one is working and they are the same that were used in this project when it was working.

This has been happening since I switched from Gradle to Maven, but since that's a completely different system, it's not a very useful comparison I believe.

When I run mvn --batch-mode --settings .circleci/settings.xml dependency:go-offline install -e -X on my own computer, after deleting ~/.m2/repository, the output looks like this: https://gist.github.com/pupeno/da4f53a6e9673ff611909021306191a4#file-maven-local-machine-log and when I do the same in CircleCI, it looks like this: https://gist.github.com/pupeno/da4f53a6e9673ff611909021306191a4#file-maven-circleci-log

When listing the repositories present, following the answer at How can I ask Maven for a list of the default repositories?, I see this:

I have logging enabled for this bucket and one entry looks like this (with the expected 404):

These are the last 3 accesses to maven-metadata.xml:

主要问题可能是对存储库的请求太多Amazon S3。

Amazon S3通过分析日志我们可以看到在短短1-3秒的时间内就有超过120个下载文件的请求：

  • Maven 正在下载 中不存在的工件Amazon S3，然后从 中下载Maven Central，这些请求是Amazon S3无用的
  • 每次下载都需要登录和注销请求，这很奇怪！
  • 最后 40 个请求连接被拒绝
  • 最后 40 个请求没有[INFO] 登录 - projectx-support 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个解决方案：

  1. 强制maven首先从下载artefact Maven Central，然后从中休息Amazon S3，以减少对Amazon S3. 这是一个很好的解决方案，但请记住，如果您有更多的工件可供下载，那么Amazon S3您只会遇到同样的问题！

    默认情况下，它在存储库中Maven Central排在最后，要设置最高优先级并首先从 中下载Maven Center，我们必须手动将其添加到存储库中的第一个位置，因为存储库的顺序也将决定存储库访问的顺序。（来源）：

  2. 找到一种方法来更改存储库上IPAmazon S3的请求限制 。此解决方案始终有效，但您的 Amazon S3 将收到许多无用的请求。

所以解决这个问题的最好方法就是混合这两种解决方案。:)
