Java 创建 Maven 项目，无法解析原型，连接被拒绝

Create Maven project, could not resolve archetype, connection refused

提问by DamienL

I suspect that I have a Maven proxy problem. When I create a new project :

我怀疑我有 Maven 代理问题。当我创建一个新项目时：

1) File -> New -> Maven Project

1) 文件 -> 新建 -> Maven 项目

2) I choose the archetype: in org.apache.maven.archetypes -> maven-archetype-webapp

2）我选择原型：在 org.apache.maven.archetypes -> maven-archetype-webapp

3) And I get this error :

3）我收到这个错误：

Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.

Creating maven-archetype-webapp' has encountered a problem. Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webap p:RELEASE from any of the configured repositories.

无法从任何配置的存储库解析原型 org.apache.maven.archetypes:maven-archetype-webapp:RELEASE。

创建 maven-archetype-webapp' 遇到问题。无法从任何配置的存储库解析原型 org.apache.maven.archetypes:maven-archetype-webap p:RELEASE。

1)窗口 -> 首选项 -> 常规 -> 网络连接。我在手册中输入了我的HTTP协议代理的URL和端口。之所以有效，是因为在此之前，Spring Tool Suite 不想更新。之后就好了

2)窗口 -> 首选项 -> Maven -> 用户设置。在全局设置中，为空。在User Settings 中，我将路径放在settings.xml 中。在这个文件中，我有：

In this topic : Create a Maven project in Eclipse complains "Could not resolve archetype"The problem was solved with adding the remote catalog http://repo1.maven.org/maven2/archetype-catalog.xml. For me, it said that the catalog is empty.

在本主题中： 在 Eclipse 中创建 Maven 项目抱怨“无法解析原型”通过添加远程目录http://repo1.maven.org/maven2/archetype-catalog.xml解决了问题。对我来说，它说目录是空的。

My configuration: Windows 7 Pro 64 bit, Spring tool suite 3.6.4.RELEASE based on Eclipse Luna SR1 (4.4.2), Java version 8 Update 45, No authenticated proxy

I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below:

我有同样的问题。我通过将 maven 原型目录添加到 eclipse 来修复它。步骤如下：

1. Open Window
2. Preferences Open Maven
3. Archetypes Click 'Add Remote
4. Catalog' and add the following:

1. 打开窗户
2. 首选项打开 Maven
3. 原型单击“添加远程
4. 目录”并添加以下内容：

Catalog File: http://repo1.maven.org/maven2/archetype-catalog.xml

Description: maven catalog

目录文件：http: //repo1.maven.org/maven2/archetype-catalog.xml

描述：maven 目录

I had the same problem, I think in a certain time you tried to create that maven app without connection like me and that what causes this problem. Because the first time Maven creates an empty directory try to download whatever it needs to create the project ..after that any maven project you create, Maven keeps looking just in that directory whitout downloading things from the internet. I beleive the easiest way to solve this problem is to close Eclipse(or sts) and delete the .m2 directory located in (in my case) "c:/Users/myname/.m2". and then reopen the IDE you were using. Good luck

我遇到了同样的问题，我想在某个时间你试图像我一样创建没有连接的 maven 应用程序，这就是导致这个问题的原因。因为第一次 Maven 创建一个空目录时，会尝试下载创建项目所需的任何内容......在您创建的任何 Maven 项目之后，Maven 一直在该目录中查找，而不会从 Internet 下载内容。我相信解决这个问题的最简单方法是关闭 Eclipse（或 sts）并删除位于（在我的情况下）“c:/Users/myname/.m2”中的 .m2 目录。然后重新打开您正在使用的 IDE。祝你好运

i also had the same problem, i resolved it by deleting .m2in c:/user/{user_name}/.m2

我也有同样的问题，我通过删除解决.m2了 c:/user/{user_name}/.m2

i hope it can help.

我希望它能有所帮助。

Restart your eclipse after changing proxy settings in c:/user/{user_name}/.m2

更改 c:/user/{user_name}/.m2 中的代理设置后重新启动 Eclipse

It seems like Maven tries to find the jar for the relative webapp (or quickstart, in some cases) and when it cannot find it, it throws this error. As per the documentation available Maven should install all the required files / jars automatically, but for whatever reason it can't in several cases.

似乎 Maven 试图为相关的 webapp（或快速入门，在某些情况下）找到 jar，当它找不到它时，它会抛出这个错误。根据可用的文档，Maven 应该自动安装所有必需的文件/jar，但无论出于何种原因，在某些情况下都无法安装。

I downloaded "maven-archetype-webapp-1.0.jar" from hereand placed it at the following location in my .m2 folder, and it worked:

我从这里下载了“maven-archetype-webapp-1.0.jar”并将其放置在我的 .m2 文件夹中的以下位置，它工作正常：

<Your path up until .m2>\.m2\repository\org\apache\maven\archetypes\maven.archetype.webapp

回答by GAGAN GOWDA

Delete the .m2 folder in C:\User\user_name. Hope this will solve the problem.

删除 C:\User\user_name 中的 .m2 文件夹。希望这能解决问题。
