A simple command line to download a remote maven2 artifact to the local repository? 3 answers

一个简单的命令行,用于将远程maven2工件下载到本地存储库? 3个答案

I would like something like the following.

我想要像下面这样的东西。

I want just an utility that is able to download jars and their dependencies from the Maven Repository without imposing no constraints on how my project should be built.

我只想要一个能够从Maven存储库下载jar及其依赖项的实用程序,而不对我的项目应该如何构建施加任何限制。

I would like something like this:

我想要这样的东西:

download-jar --dest=lib/ 'commons-io:commons-io:jar:1.4'

It should be able to download also the dependencies.

它应该能够下载依赖项。

Update:

I wouldn't know about a pom.xml should be structured.

我不知道应该构建一个pom.xml。

The only task I need to be accomplished is the download of the jars, I would like have a tool that could accomplish this task that doesn't bother me with superflous information.

我需要完成的唯一任务是下载罐子,我想有一个工具可以完成这项任务,不会给我带来超级信息。

There is something like that?

有类似的东西?

If you want to download maven dependencies into your lib directory use the dependency plugin with the copy-dependencies function.

如果要将maven依赖项下载到lib目录中,请使用带有copy-dependencies函数的依赖项插件。

mvn -DoutputDirectory=./lib -DincludeArtifactIds=commons-logging,commons-io dependency:copy-dependencies

Without the -DincludeArtifactIds part you'll download every dependency.

如果没有-DincludeArtifactIds部分,您将下载每个依赖项。

If you want to download a an artifact without having a specific project *see below** :

如果您想在没有特定项目的情况下下载工件*请参阅下面**:

mvn -DgroupId=commons-io -DartifactId=commons-io -Dversion=1.4 dependency:get

Resources :

maven.apache.org - dependency:copy-dependencies

maven.apache.org - 依赖:copy-dependencies

force Maven2 to copy dependencies into target/lib

强制Maven2将依赖项复制到target / lib中

maven.apache.org - dependency:get *see below**

maven.apache.org - 依赖:get *见下文**

*@Pascal Thivent :

No need to setup a POM, no need to develop your own tool, use mvn dependency:get. That's the right answer to this question.

无需设置POM,无需开发自己的工具,使用mvn依赖:get。这是这个问题的正确答案。

I also had to specify -DrepoUrl, after getting the error message:

在收到错误消息后,我还必须指定-DrepoUrl:

Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.1:get 
  (default-cli) on project standalone-pom: The parameters 'repositoryUrl' 
  for goal org.apache.maven.plugins:maven-dependency-plugin:2.1:get are 
  missing or invalid -> [Help 1]

So here is the command I used:

所以这是我使用的命令:

mvn -DgroupId=edu.umd -DartifactId=cloud9 -Dversion=1.3.5 \
  -DrepoUrl="http://repo1.maven.org/maven2" dependency:get

Furthemore, -Ddest=~ didn't work. It always insisted on installing the jar to ~/.m2/repository.

更进一步,-Ddest =〜没有用。它始终坚持将jar安装到〜/ .m2 / repository。

Maven3 uses dependency plugin v2.1 by default:

Maven3默认使用依赖插件v2.1:

$ mvn dependency:get -DrepoUrl=http://download.java.net/maven/2/ \
   -DgroupId=commons-io -DartifactId=commons-io -Dversion=1.4

With Maven2 is still necessary to write the canonical name:

使用Maven2仍然需要编写规范名称:

$ mvn2 org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
   -DrepoUrl=http://download.java.net/maven/2/ \
   -DgroupId=commons-io -DartifactId=commons-io -Dversion=1.4

Use parameter artifact to set the name of the artifact as group:artifact:version:

使用参数工件将工件的名称设置为group:artifact:version:

$ mvn dependency:get -DrepoUrl=http://download.java.net/maven/2/ \
   -Dartifact=commons-io:commons-io:1.4

Use LATEST to download the latest version of the artifact:

使用LATEST下载最新版本的工件:

$ mvn dependency:get -DrepoUrl=http://download.java.net/maven/2/ \
   -Dartifact=commons-io:commons-io:LATEST

You should take a look at the maven dependency plugin, maybe ... and especially its go-offline mojo

你应该看一下maven依赖插件,也许......尤其是它的go-offline mojo

Have a look at Ivy. It allows dependency resolution from maven repositories without the overkill complexity of maven itself.

看看常春藤吧。它允许从maven存储库中进行依赖性解析,而不会出现maven本身的过度复杂性。
