我检查了一个 Maven 项目，Return code is: 500, ReasonPhrase:Internal Server Error.当我尝试编译它时它给了我一个“”。奇怪的是，对于同事来说，完全相同的工作却没有问题。我可以在这里做什么？

我的 Maven 输出

autosparql-lite$ mvn clean compile

我的 settings.xml

PS：

我的 Maven 版本

Apache Maven 3.0.4 (rNON-CANONICAL_2012-01-24_13-02_root; 2012-01-24 14:02:02+0100)
Maven home: /opt/maven
Java version: 1.7.0_03-icedtea, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk/jre
Default locale: de_DE, platform encoding: UTF-8
OS name: "linux", version: "3.0.26-1-lts", arch: "amd64", family: "unix"

他的 Maven 版本

Apache Maven 2.2.1 (rdebian-4)
Java version: 1.7.0
Java home: /usr/lib/jvm/jdk1.7.0/jre
Default locale: de_DE, platform encoding: UTF-8
OS name: "linux" version: "2.6.38-13-generic" arch: "amd64" Family: "unix"

PS：这和我们的maven版本有关系吗？我使用 Maven 3，他使用 Maven 2。这个语义科学服务器来自哪里？

PPS：好的，我终于摆脱了语义科学存储库，方法是从我的 pom.xml 中删除它并删除 ~/.m2/repository 文件夹。现在我得到另一个错误，见下文。

奇怪的是，以下网址可以在浏览器中解析：

但是 ping 不起作用：

$ ping http://repo.aduna-software.org
ping: unknown host http://repo.aduna-software.org
$ ping http://repo.aduna-software.org/maven2/releases
ping: unknown host http://repo.aduna-software.org/maven2/releases

但这不是 ping 的错：

$ ping www.google.de
PING www-cctld.l.google.com (173.194.69.94) 56(84) bytes of data.
64 bytes from bk-in-f94.1e100.net (173.194.69.94): icmp_req=1 ttl=48 time=13.3 ms
[...]

这是错误：

Failed to read artifact descriptor for org.openrdf.sesame:sesame-sail-memory:jar:2.4.0: Could not transfer artifact org.openrdf.sesame:sesame-sail-memory:pom:2.4.0 from/to aduna-software-release-repo (http://repo.aduna-software.org/maven2/releases): repo.aduna-software.org: Der Name oder der Dienst ist nicht bekannt: Unknown host repo.aduna-software.org: Der Name oder der Dienst ist nicht bekannt

我尝试了http://wiki.tuxtorials.de/wiki/Ping:_unknown_host告诉我的并做了

echo "echo \"hosts:      files dns\" > /etc/nsswitch.conf" | sudo sh

但这也无济于事。

好的，我不知道为什么，但现在它对我有用。但我想知道为什么...

您必须在某处配置了一个 Maven 代理，名称为http://s1.semanticscience.org:8080/nexus/

可能在您的其中一个 settings.xml 文件中，$HOME/.m2或者$MAVEN_HOME/conf/.

当 Maven 尝试从那里检索 gxt-2.2.5 时，Nexus 服务器似乎回复了错误 500。我会再试一次，如果它仍然不起作用，请检查浏览器中的 URL，并可能与该 Nexus 安装的管理员交谈。

您正在尝试com.extjs:gxt:pom:2.2.5从http://s1.semanticscience.org:8080/nexus/content/groups/public/com/下载，但在 Nexus 存储库中不可用。

我怀疑您的同事一定是从另一个存储库中检索该工件，但您不是。查看他可能已配置的任何其他存储库，或者您遗漏的任何其他存储库。
