root module

打开intellij新建maven工程，待maven工程全部生成完成之后，在pom.xml中添加以下内容。

以上均是搭建环境所必须的相关依赖，因为本环境并不仅仅是进行几个osgi的example的编写，因此搭建环境比较复杂。在以上依赖添加完之后，还需要将pom.xml中的packaging改为pom，并且删去工程下的src文件夹，本工程为root模块，不需要写代码。

---

parent module

新建maven module为当前工程的子module，命名为parent，与上述module相同的是，parent同样是一个父module，因此删除目录下src文件夹，仅保留pom.xml,同时在pom.xml中添加如下内容：

以上基本就是我们当前需要添加的所有依赖，在当前还添加了个别项目中的模块，这些是在后续中将添加的，当前报错的地方可以先注释起来。
并且注意maven插件中的karaf-tooling这一个插件，这个就是提供osgi的运行容器karaf，在后文的编写中，这个将起到非常重要的作用，同时maven-resources-plugin这一个插件管理我们项目中其他资源的位置，在日后的编写中也将会提到这个。当然上文中也必少不了felix这一个插件，在后文中编写felix官网中的example时，这个将不时出现。

feature module

再次在root module下新建maven工程，命名为feature module，这一个尤其重要，这个module中，将对具体的feature进行管理，feature是一批bundle的集合，同时也在管理接下来中的子module中所需的其他feature依赖和bundle。
管理这些feature需要一个单独的xml配置文件，删除src下的main文件夹，保留resource文件夹，新建xml命名为feature.xml,添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<features name="karaf-swagger-${project.version}"
          xmlns="http://karaf.apache.org/xmlns/features/v1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0
        http://karaf.apache.org/xmlns/features/v1.0.0">


</features>

现在这个feature.xml中没有管理任何featue，在后文中将会添加其他featue进来。现在是最基本的配置。
在新建完feature之后，在pom文件中添加以下内容：

    <properties>
        <deploy.file>${project.build.directory}/classes/features.xml</deploy.file>
    </properties>

    <build>
        <defaultGoal>install</defaultGoal>

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <executions>
                    <execution>
                        <id>filter</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>resources</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>
                <version>1.9.1</version>
                <executions>
                    <execution>
                        <id>attach-artifacts</id>
                        <phase>package</phase>
                        <goals>
                            <goal>attach-artifact</goal>
                        </goals>
                        <configuration>
                            <artifacts>
                                <artifact>
                                    <file>${deploy.file}</file>
                                    <type>xml</type>
                                    <classifier>features</classifier>
                                </artifact>
                            </artifacts>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

以上内容是指定feature.xml文件位置以及相应对该文件进行操作的插件，在以上完成之后，需要改当前pom的parent为parent module，同时在parent module中添加module为feature。

总结

以上完成之后，基本的环境搭建基本就完成了，具体的编码module的创建，还有karaf输出日志的的规定，将在下次博文中编写，本文仅只搭建基本的运行环境。
