我正在关注一个很棒的教程: http://www.objectdb.com/tutorial/jpa/eclipse/spring/project
在复制pom.xml的代码后的第一步,我得到9个错误.这是我的pom.xml第1行显示的错误:
Failure to transfer org.apache.maven.reporting:maven-reporting-api:jar:2.0.6 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. Original error: Could not transfer artifact org.apache.maven.reporting:maven-reporting-api:jar:2.0.6 from/to central (http://repo.maven.apache.org/maven2): The operation was cancelled. pom.xml /Guestbook line 1 Maven Configuration Problem
如有必要,我可以发布其他错误.我之前尝试过运行一些简单的预制maven项目,我相信他们称之为archtypes.他们有类似的错误.我不明白为什么会这样,我不能得到一些你好世界的东西不立即抛出错误.
我正在将项目迁移Jboss 5.1到jboss 7.1
我有两个EAR,运行在同一个Jboss上.它们包含内部的ejb项目,并且services.jar由于finalname标记而调用了两个ejb jar文件 EJB_PROJECT/pom.xml
<build>
<finalName>services</finalName>
.....
</build>
在Jboss 5.1上它工作正常,但现在我得到错误:

at …我在Java Maven项目中工作..bat项目的根目录中有一个文件调用Java类,其中包含一些类似这样的参数:
java my.package.MyClass abc hi 1
现在,当我这样做时,我的项目jar就构建在该项目的目标目录中mvn clean install.当我运行该.bat文件时,它给出了以下错误
Error: Could not find or load main class my.package.MyClass
Project pom.xml仅包含jar作为依赖项.
有人可以帮我解决这个问题.我需要做些什么pom.xml才能让它发挥作用.

我正在尝试学习 Spring Boot 实践，并使用我的 IntelliJ IDE 通过 Spring Starter 导入基本 Spring Boot 应用程序的样板，但 Maven 无法解析所有依赖项，并且我的项目错过了重要的依赖项。我不明白这是什么原因。
首先，我认为问题出在使用 JDK8 作为较新版本的 SpringFramework，然后我安装了 JDK11，但同样的问题仍然存在，据我所知 POM.xml 列出了其中的所有依赖项。
