我在其他计算机上导入了我的工作项目,因此它开始下载依赖项.

显然在此期间我的互联网连接崩溃了.现在我得到:

为漫画构建错误; org.apache.maven.lifecycle.LifecycleExecutionException:无法在项目漫画上执行目标测试:无法解析项目漫画的依赖项测试:漫画测试:war:0.0.1-SNAPSHOT:无法解析以下工件:org.springframework:spring- context:jar:3.0.5.RELEASE,org.hibernate:hibernate-entitymanager:jar:3.6.0.Final,org.hibernate:hibernate-core:jar:3.6.0.Final,org.hibernate:hibernate-commons-注释:jar:3.2.0.Final,org.aspectj:aspectjweaver:jar:1.6.8,commons-lang:commons-lang:jar:2.5,

原始错误:无法传输工件org.springframework:spring-context:jar:3.0.5.RELEASE from central(http://repo1.maven.org/maven2):60000后没有收到回复

我不知道如何强制maven更新？

有了maven,我偶尔会看到一些来自我尚未构建或包含在我的存储库中的第三方存储库的工件.

我将从maven客户端收到一条错误消息,指出无法找到工件:

未能找到org.jfrog.maven.annomojo:maven-plugin-anno:jar:1.4.0 in http://myrepo:80/artifactory/repo缓存在本地存储库中,在MyRepo的更新间隔过去或强制更新之前,不会重新尝试解析 - > [帮助1]

现在,我理解这意味着什么,并且可以简单地重新运行我的命令-U,并且通常在那里工作正常.

但是,我发现这个错误信息非常不直观,并且试图让我的同事们感到头疼.

我想知道是否有一些地方可以修改此update interval设置.

1. 在update interval此错误消息的客户端或服务器端的设置,被提及？
2. 如果是客户端,我该如何配置呢？
3. 如果是服务器端,是否有人知道如何/如果Nexus/Artifactory公开这些设置？

我想分享我通过代理使用maven的经验.

您很可能会遇到异常和消息,例如:

repository metadata for: 'org.apache.maven.plugins' could not be retrieved from 
repository: central due to an error: Error transferring file: Connection refused: connect

要么

[WARNING] Failed to retrieve plugin descriptor for org.apache.maven.plugins:maven-clean-
plugin:2.5: Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its 
dependencies could not be resolved: Failed to read artifact descriptor for 
org.apache.maven.plugins:maven-clean-plugin:jar:2.5

如何配置Maven使用代理服务器？

我试图在我的pom中引入对castor库的依赖.由于我的项目处于初步阶段,所有工件都来自maven central.所以我在search.maven.org上搜索"castor".我取第一个结果,它给了我以下依赖片段:

<dependency>
    <groupId>org.codehaus.castor</groupId>
    <artifactId>castor</artifactId>
    <version>1.3.3</version>
</dependency>

现在我"mvn clean install"并获得以下内容:

[ERROR] Failed to execute goal on project jaxb: Could not resolve dependencies for project org.test:jaxb:war:0.0.1-SNAPSHOT: Could not find artifact org.codehaus.castor:castor:jar:1.3.3 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

为什么CLI无法找到可从Web界面找到的工件.我当然错过了一些东西.请求指出它可能是什么.

在其他帖子中,我已经调查了这个和这个相关的帖子,但不是这个问题.

但是当我运行maven build时,我遇到了以下错误.有人可以请帮助

最近我从Archiva迁移到了Sonatype Nexus.

我正在尝试使用来自第三方存储库的Jars,而Nexus不会将其缓存到本地存储库中.

我已经在本节中搜索了答案,而且无法回答这个问题.

这就是我做的......

我正在使用settings.xml:

我在构建 Farma-rest 项目时遇到问题，该项目依赖于我的其他项目 Farma。我将依赖项放入 pom.xml 中，但它无法解析项目的依赖项。它向我显示了此错误消息：
