java - Maven中央仓库: Return code is: 503 , ReasonPhrase:backend read error

Question

在我们项目的持续集成系统 (travis-ci.org) 中，我开始出现错误:

[ERROR] Failed to execute goal org.codehaus.cargo:cargo-maven2-plugin:1.4.6-SNAPSHOT:start (start-container) on project p6spy-it: Failed resolving artifact: Could not transfer artifact org.jboss.jbossas:jboss-as-distribution:zip:6.1.0.Final from/to central (http://repo.maven.apache.org/maven2): Failed to transfer file: http://repo.maven.apache.org/maven2/org/jboss/jbossas/jboss-as-distribution/6.1.0.Final/jboss-as-distribution-6.1.0.Final.zip. Return code is: 503 , ReasonPhrase:backend read error.

可以在以下位置看到完整的构建输出:https://api.travis-ci.org/jobs/15104889/log.txt?deansi=true

如果我通过浏览器访问有问题的 url:http://repo.maven.apache.org/maven2/org/jboss/jbossas/jboss-as-distribution/6.1.0.Final/jboss-as-distribution-6.1.0.Final.zip 我也遇到同样的错误:

Error 503 backend read error

然而有一天一切都很好。

我该怎么办/如何解决？只是等待他们刷新一些内部缓存？

尝试:

(1) 下载jboss-as-distribution-6.1.0.Final.pom和jboss-as-distribution-6.1.0.Final.zip Maven Central Repository .

(2) 手动将 zip 文件安装到本地 Maven 存储库。

mvn install:install-file \
    -Dfile=jboss-as-distribution-6.1.0.Final.zip \
    -DpomFile=jboss-as-distribution-6.1.0.Final.pom

似乎“返回代码是:503，ReasonPhrase:后端读取错误。”当目标 zip 文件很大时会发生错误。我在下载appengine-java-sdk-1.9.0.zip时遇到了同样的错误。
