我完全不熟悉将 Eclipse 与 Maven 一起使用，我正在尝试按照使用 Java 库的教程进行操作，但在先决条件上失败:http://code.google.com/p/dkpro-core-asl/wiki/DeveloperSetup
在最后一次单击页面的“完成”结束后，如果我查看我的 Eclipse 窗口，我认为出了点问题，因为我在 Eclipse Package Explorer 中有很多错误和一些小错误(我也没有找出红色感叹号、红色小白叉(认为这是一个错误标记)或必须是“警告符号”(黄色感叹号三角形)之间的不同点。
所以我有很多不同类型的错误，不知道如何解决它们，我复制了下面的完整日志。
我的错误是这样的:
Missing artifact de.tudarmstadt.ukp.dkpro.teaching:de.tudarmstadt.ukp.dkpro.teaching.frequency:jar:0.4.0:compile pom.xml /de.tudarmstadt.ukp.dkpro.core.api.frequency-asl line 1 Maven Problem

The project cannot be built until build path errors are resolved de.tudarmstadt.ukp.dkpro.core.api.frequency-asl Unknown Java Problem
如果你有任何关于如何解决它们的线索，请
我想知道我是否没有忘记一些基本结帐之王，因为我看起来几乎所有东西都坏了？
谢谢你

编辑:
我想我已经安装了 eclipse 安装程序(但使用 Eclipse Indigo Service Release 2 Build id:20120216-1857)按照教程的要求:
Subclipse 1.6.x
update site: http://subclipse.tigris.org/update_1.6.x
m2eclipse 0.10.0 or higher.
update site: http://m2eclipse.sonatype.org/sites/m2e
Maven SCM handler for Subclipse
update site: http://m2eclipse.sonatype.org/sites/m2e-extras
这里是 mvn clean package 命令的输出，来自有 pom.xml 文件的目录:

另一个非常奇怪的事情 => 也许“mvn dependecy:resolve”或“mvn clean package”为我做了一些事情，因为在计算机重新启动后，几乎所有错误都消失了，现在 Eclipse“问题”中只有 2 个标签 ! (但仍有225项警告)
剩下的 2 个错误是:我在包资源管理器中的 de.tudarmstadt.ukp.dkpro.core.api.frequency-asl 上有一个红色感叹号(它代表什么？)

仍然不知道它在问我什么!
最后编辑:
所以阅读 Kal 提供的答案(非常感谢您的帮助)，我真的很想知道我的麻烦是否也不是来自丢失的 jars 或一些“构建路径”引用的库(我真的是 Maven/Eclipse 的新手)。从 de.tudarmstadt.ukp.dkpro.core.api.frequency-asl 的构建错误(EDIT2 中带有红色感叹号的错误)开始，我得到以下异常跟踪:
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project de.tudarmstadt.ukp.dkpro.core.api.frequency-asl: Could not resolve dependencies for project de.tudarmstadt.ukp.dkpro.core:de.tudarmstadt.ukp.dkpro.core.api.frequency-asl:jar:1.2.1-SNAPSHOT: Failed to collect dependencies for [org.uimafit:uimafit:jar:1.2.0 (compile), xerces:xercesImpl:jar:2.9.1 (compile), xalan:xalan:jar:2.7.1 (compile), de.tudarmstadt.ukp.dkpro.teaching:de.tudarmstadt.ukp.dkpro.teaching.frequency:jar:0.4.0 (compile), junit:junit:jar:4.8.2 (compile)]
at org.apache.maven.lifecycle.internal.LifecycleDependencyResolver.getDependencies(LifecycleDependencyResolver.java:190)
[...]
难道我不应该安装 xerces、xalan、uimafit、junit 或类似的东西来告诉在哪里可以找到它们吗？我以为一切都在教程中，或者由 Maven 直接处理，但可能我错了？？？
我曾尝试过:
mvn install:install-file -Dfile=d:\downloaded\dependencies-for-DKPro-Core-ASL\junit-4.8.2.jar -Dfile=d:\downloaded\dependencies-for-DKPro-Core-ASL\uimafit-1.2.0.jar -Dfile=d:\downloaded\dependencies-for-DKPro-Core-ASL\xalan-2.7.1.jar -Dfile=d:\downloaded\dependencies-for-DKPro-Core-ASL\xercesImpl-2.9.1.jar \
从 mvnrepository.com 网站手动下载每个文件并将它们放入 d:\downloaded\dependencies-for-DKPro-Core-ASL\ 当然，我在那里找不到 de.tudarmstadt.ukp.dkpro.teaching:de.tudarmstadt.ukp.dkpro.teaching.frequency:jar:0.4.0。

还看到有人提示:“依赖关系解析无法正常工作。新的 m2eclipse 插件直到最后才解析依赖关系。”这可能涉及？
而且我仍然严重卡住:/而且对于 maven/java/eclipse 平台技巧来说仍然太新......
最佳答案
首先，您似乎有一些似乎是专有的依赖 jar(我可能错了)，其次，甚至无法下载像 Apache 库这样的公共(public)库。你在防火墙后面吗？看起来 Maven 无法访问 Maven Central 以下载所有依赖项 jar 和插件。确保您使用的是与您的项目兼容的正确版本的 Maven。
如果您正在检查一个巨大的项目，我建议您首先在控制台中进行顶级构建(mvn clean package)。这将确保下载所有插件和依赖项，然后您可以解决将此项目导入 Eclipse 的问题。或者，您可以执行 mvn dependency:resolve 来下载所有依赖项。
关于java - Maven 和 Eclipse 集成的错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10206005/
