我正在使用命令行中的maven-dependency-plugin来下载单个文件,但是在我的本地存储库中,对于我的特定用例,我希望将它下载到当前目录.
我正在使用该插件的2.4版,它应该支持-Ddestination作为备用下载站点; 但是,我无法让它发挥作用.在调试模式下运行maven似乎表明目标参数被忽略...
我正在运行以下内容:
M:\>mvn -e -X org.apache.maven.plugins:maven-dependency-plugin:2.4:get \
-Ddestination=M:\test \
-DremoteRepositories=http://nexus-repo:8080/nexus/content/repositories/snapshots \
-Dartifact=com.company.Common:CommonLibs:1.12.0-SNAPSHOT:tar \
-Dtransitive=false
......但得到这个......

[DEBUG] …我包装了EJB,我需要包括从依赖到罐子一些.classes,我试图使用Maven的依赖,插件解压神器将文件放在我的$ {project.build.directory在包阶段期间/ classes目录,但是当我执行mvn包时,我没有看到任何日志或对maven-dependency-plugin的引用(没有任何反应),我甚至尝试使用无效版本的插件,它甚至没有抛出异常.

我错过了什么？
PS:工件模型安装在本地仓库中,我也尝试过其他阶段.
我正试图从我的POM获得一个简单的,机器可解析的依赖项列表.如果我做:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:list -f sample.pom
我得到了无意义的[INFO]输出:

然后我必须手动刮取信息.如果我添加-q开关
mvn -q org.apache.maven.plugins:maven-dependency-plugin:2.1:list -f sample.pom
如果它已经是本地的,我会得到一个下载进度消息或什么都没有(除非当然有错误).
是否真的没有办法执行依赖列表命令,所以它只输出一个简单的下载依赖列表？就像是:
> mvn …我需要从一个依赖的jar文件到我的当前项目的输出目录的根目录的根目录复制的资源文件(menu.xml文件),在生成过程中被执行的测试之前.该文件必须可用于测试,但稍后也可用于主程序...getClassLoader().getResourceAsStream("menu.xml").
我正在尝试在这个问题中提出的解决方案,但它不起作用.
这是pom文件的样子:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>resource-dependencies</id>

<outputDirectory>${project.build.outputDirectory}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
当我执行时,mvn clean process-test-resources我看到以下输出:
[INFO] --- maven-resources-plugin:2.7:testResources (default-testResources) @ pm1-config ---

[INFO] ------------------------------------------------------------------------ …我想用我的主要Java项目及其所有依赖项创建一个jar文件。所以我在pom文件中创建了以下插件定义：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.5.1</version>
<executions>
<execution>
<id>copy-dependencies</id>

<!-- exclude junit, we need runtime dependency only -->
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.directory}/dependency-jars/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
所以我执行mvn dependency:copy-dependencies，将所有的依赖复制到target/dependency而不是复制上很好dependency-jars。有任何想法吗？
我试图在实际使用它们之前从maven项目下载所有插件依赖项.
我试过跑:
mvn dependency:resolve-plugins
这成功下载了它的插件和部分依赖项.例如,对于exec插件,我得到:
...

[INFO] Plugin Dependency Resolved: …我们不需要指定我们使用的Maven依赖项和插件的版本和其他参数。我们只能在父 POM 中执行一次，或者可以通过其他方式在子 POM 中继承该属性。
不幸的是，我多次遇到无法轻松找到依赖项和插件的真实参数的项目。即依赖项的版本为空，但在父 POM 中没有有关此的信息。
所以我的问题是：
在Maven中指定依赖和插件的参数有哪些可能的方式？即，如果版本号既不存在于子 POM 的插件中，也不存在于父 pom 的插件管理中，我可以在哪里查找版本号？
有没有 Maven 命令可以找出 Maven 从哪里获取这些参数？例如，我可能会使用该dependency:tree命令。它将打印一个依赖项列表，这将帮助我理解我所困扰的版本依赖项。但这是一个黑客，它不能帮助我使用插件。也许有更好的东西？
如何使用maven依赖插件,unpack-dependecies目标解压缩到绝对路径,即在项目树中生成的目标文件夹中不相对？例如,我想在/ usr/local/*中解压缩下面两个依赖项的工件
<dependencies>

当我构建 maven 项目时，有没有一种方法可以根据给定的条件设置依赖项。
mvn package someCondition
因此，如果我说mvn install A它应该添加一个依赖项，如果说mvn install B它应该添加另一种类型的依赖项。
请帮忙。谢谢你
PS 有没有办法通过创建多个配置文件来做到这一点？
