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？
我正在尝试使用Maven(m2eclipse)设置项目,但我在Eclipse中遇到此错误:
说明资源路径位置类型无法计算构建计划:无法传输org.apache.maven.plugins:来自http://repo1.maven.org/maven2的 maven-compiler-plugin:pom:2.0.2 已缓存在本地存储库,在中心的更新间隔过去或强制更新之前,不会重新尝试解析.原始错误:无法传输工件org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from/to central(http://repo1.maven.org/maven2):在60000 ExampleProject之后没有收到响应未知的Maven问题
有任何想法吗？如果你能告诉我如何检查一切是否配置好会有所帮助...
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？
这应该是我朋友的一个工作项目.他在我面前展示了项目,然后我复制了项目,将其作为现有的maven项目导入(我使用的是m2eclipse插件).
然后,发生此错误.每次我尝试使用maven构建内容时都可以重现此错误.
执行mvn依赖:tree,dependency:list或通常的构建包将导致相同的错误.
从eclipse运行'package'构建的错误是:

我有一个带有"主"POM的多模块maven项目,它是Spring Boot Parent模块的子项.看起来像这样:
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>project</artifactId>
<packaging>pom</packaging>
<version>0.1.0</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.0.BUILD-SNAPSHOT</version>
<relativePath/>
</parent>
<modules>
<module>module1</module>
<module>module2</module>
<module>module3</module>
</modules>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<start-class>com.example.module1.Application</start-class>
<java.version>1.8</java.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
这基本上是我们的"主人"POM,每个孩子都使用它作为它的父母.现在我们spring-boot:run要从这个"主"POM所在的工作目录中执行命令.问题是,这会生成一个ClassNotFoundException奇数,因为module1(此类Application所在的位置)包含在POM中并作为模块提及.
使用单个模块maven项目,<packaging>jar</packaging>这将编译并运行Application类,因此Spring-Boot不是在这里工作.
spring-boot-maven-plugin在处理多模块Maven项目时,我需要更改什么才能使其工作或者根本无法使用插件？
旁注:我的应用程序类/模块1将其他模块作为依赖项,因此在回答问题时请记住这一点.任何关于如何改进这一点的建议都非常感谢.
我在我的pom.xml的第一行中遇到错误
Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.

</parent>
我也试着留下relativePath空白，或者../或者..甚至不包括它在所有。在所有情况下，结果是：
