使用Spring Framework Cloud时，无法将工件从/向*maven repo传输

I am trying to create a maven project using Spring Framework Cloud. I defined pom.xml file as below

When I go to the location, I can clearly see the Jar files are present in that location. Is there something else I need to add to my pom.xml?

当我去该位置时,我可以清楚地看到Jar文件存在于该位置。我需要在pom.xml中添加其他内容吗?

2 个解决方案

#1

Try force refreshing your dependencies. Specifying -U does that

尝试强制刷新您的依赖项。指定-U会这样做

mvn clean install -U

Edit: You can purge your local release dependencies and to the normal mvn clean install afterwards:

编辑:您可以在之后清除本地版本依赖项和正常的mvn clean install:

mvn dependency:purge-local-repository

There is not way to force the release dependencies to be pulled, the -U only works with snapshot dependencies

没有办法强制释放依赖项,-U仅适用于快照依赖项

#2

I tried the same pom.xml inEclipse IDE and surprisingly it worked there as it is.

我在Eclipse IDE中尝试了相同的pom.xml,令人惊讶的是它在那里工作。

To make it work on STS, I added following properties

为了使它适用于STS,我添加了以下属性

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <start-class>io.pivotal.microservices.services.Main</start-class>
        <spring-cloud.version>Brixton.RELEASE</spring-cloud.version>
    </properties>

Refer Unable to download/import package org.springframework.cloud.config.server.EnableConfigServer

参考无法下载/导入包org.springframework.cloud.config.server.EnableConfigServer

This worked for me, though I am still curious about the difference.

虽然我仍然对这种差异感到好奇,但这对我有用。
