检索每个与Karaf Maven插件的依赖项并创建Karaf存档

我正在使用ServiceMix 6.1.0（包含Karaf 3.0.5），并且我有一个Maven项目。我想用karaf-maven-plugin创建卡拉夫档案（.kar）。检索每个与Karaf Maven插件的依赖项并创建Karaf存档

我明白了使用Karaf Archive的目标：检索每个依赖关系，以便.kar可以部署在脱机环境中。嗯...我想我已经明白了...创建.KAR和部署之后，我得到一个错误：

Error executing command: Can't install feature karafMavenPlugin/0.0.0: 
Could not start bundle mvn:org.testng/testng/6.8.8 in feature(s) karafMavenPlugin-0.0.1-SNAPSHOT: 
Unresolved constraint in bundle org.testng [371]: 
Unable to resolve 371.0: 
missing requirement [371.0] osgi.wiring.package; (osgi.wiring.package=org.junit)

这里是pom.xml：

这里是产生feature.xml：

     <bundle>mvn:com.beust/jcommander/1.27</bundle> 
    </feature> 
</features>

为什么JUnit的依赖没有回收？

我的猜测是，karaf-maven-plugin不pom.xml这是<optional>或<provided>检索的依赖。事实上，JUnit是一个TestNG的依赖，这里是TestNG的pom.xml（只依赖）：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> 

    <modelVersion>4.0.0</modelVersion> 
    <groupId>org.testng</groupId> 
    <artifactId>testng</artifactId> 
    <packaging>jar</packaging> 
    <name>TestNG</name> 
    <version>6.8.8</version> 
    <description>TestNG is a testing framework.</description> 
    <url>http://testng.org</url> 

    <dependencies> 
    <dependency> 
     <groupId>org.apache.ant</groupId> 
     <artifactId>ant</artifactId> 
     <version>1.7.0</version> 
     <optional>true</optional> 
    </dependency> 

    <dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>4.10</version> 
     <optional>true</optional> 
    </dependency> 

    <dependency> 
     <groupId>org.beanshell</groupId> 
     <artifactId>bsh</artifactId> 
     <version>2.0b4</version> 
<!-- 
     <scope>provided</scope> 
--> 
    </dependency> 

    <dependency> 
     <groupId>com.google.inject</groupId> 
     <artifactId>guice</artifactId> 
     <version>2.0</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>com.beust</groupId> 
     <artifactId>jcommander</artifactId> 
     <version>1.27</version> 
    </dependency> 
     <dependency> 
     <groupId>org.yaml</groupId> 
     <artifactId>snakeyaml</artifactId> 
     <version>1.12</version> 
     <optional>true</optional> 
     </dependency> 
    </dependencies>  
</project>

我们可以看到，每一个谁是依赖不<optional>而不是<provided>由karaf-maven-plugin检索。

所以...我错了吗？这是一种预期的行为吗？如果是这样的话，有没有办法指示karaf-maven-plugin下载每的依赖关系？

随着人们scope Maven的文档中描述：

提供

这很像编译，而是指你所期望的JDK或容器，以提供在运行时的依赖。例如，为Java Enterprise Edition构建Web应用程序时，您将将依赖于Servlet API和相关Java EE API 设置为提供的范围，因为Web容器提供了这些类。此范围仅在编译和测试类路径上可用，且不可传递。

'provided'不是传递性的：当通过api询问maven依赖关系时，不会检索提供的依赖关系。

所以，为了与karaf-maven-plugin一起工作，你必须在pom中明确地添加这个依赖。
