[英]Maven 3 ignores defined Remote Repository and fails to download snapshot artifact
I am attempting to use a snapshot version of a Groovy compiler from codehaus snapshot repository as specified here -but cannot seem to make maven see the artifact in the repository. 我尝试使用此处指定的来自Codehaus快照存储库的Groovy编译器的快照版本-但似乎无法使Maven看到存储库中的工件。
I have the following plugin configuration: 我有以下插件配置:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<!-- 2.8.0-01 and later require maven-compiler-plugin 3.1 or higher -->
<version>3.1</version>
<configuration>
<compilerId>groovy-eclipse-compiler</compilerId>
<!-- set verbose to be true if you want lots of uninteresting messages -->
<!-- <verbose>true</verbose> -->
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-compiler</artifactId>
<version>2.9.0-01-SNAPSHOT</version>
</dependency>
<!-- for 2.8.0-01 and later you must have an explicit dependency on groovy-eclipse-batch -->
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-batch</artifactId>
<version>2.2.1-01-SNAPSHOT</version>
<!-- or choose a different compiler version -->
<!-- <version>1.8.6-01</version> -->
<!-- <version>1.7.10-06</version> -->
</dependency>
</dependencies>
</plugin>
<plugin>
And my repositories section shows the following information: 我的存储库部分显示以下信息:
<repository>
<id>Nexus Codehaus</id>
<url>http://nexus.codehaus.org/snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
However, when I run mvn -U clean install I get the following message: 但是,当我运行mvn -U clean install时,出现以下消息:
[WARNING] The POM for org.codehaus.groovy:groovy-eclipse-compiler:jar:2.9.0-01-SNAPSHOT is missing, no dependency information available
[WARNING] The POM for org.codehaus.groovy:groovy-eclipse-batch:jar:2.2.1-01-SNAPSHOT is missing, no dependency information available
I also see the following when building the modules 构建模块时,我还会看到以下内容

It appears maven is trying to download the artifacts from a repository that I have not even defined! 看来maven正在尝试从我什至没有定义的存储库中下载工件! Why would this occur?
为什么会发生这种情况?
If I browse the repository I can see a POM as well as the various snapshot jars, so I can see no reason why this would not work. 如果浏览存储库,我会看到一个POM以及各种快照jar,因此我看不到为什么它不起作用。 Am I missing something in my repository declaration?
我在存储库声明中缺少什么吗?
Apparently when you want to download a maven plugin from a remote repository -as opposed to a standard artifcat, you have to define a special pluginRepositories section in your pom; 显然,当您想从远程存储库下载Maven插件时-与标准artifcat相对,您必须在pom中定义一个特殊的pluginRepositories部分; a plain Repository declaration will just be ignored.
普通的存储库声明将被忽略。
