一、环境信息：
Windows 10 + maven3.3.9 + JDK1.8，详细信息如下：

二、使用Archetype构建项目过程
1. 使用Archetype构建基于openDaylight-carbon版本的项目
mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeRepository=http://nexus.opendaylight.org/content/repositories/opendaylight.release -DarchetypeCatalog=remote -DarchetypeVersion=1.3.0-Carbon
并在后续的提示框中输入相关的值：
生成的目录结构树如下所示(tree命令)
example
├─api
│ └─src
│ └─main
│ └─yang
├─artifacts
├─cli
│ └─src
│ └─main
│ ├─java
│ │ └─org
│ │ └─opendaylight
│ │ └─example
│ │ └─cli
│ │ ├─api
│ │ ├─commands
│ │ └─impl
│ └─resources
│ └─org
│ └─opendaylight
│ └─blueprint
├─features
│ └─src
│ └─main
│ └─features
├─impl
│ └─src
│ ├─main
│ │ ├─java
│ │ │ └─org
│ │ │ └─opendaylight
│ │ │ └─example
│ │ │ └─impl
│ │ └─resources
│ │ └─org
│ │ └─opendaylight
│ │ └─blueprint
│ └─test
│ └─java
├─it
│ └─src
│ └─test
│ └─java
│ └─org
│ └─opendaylight
│ └─example
│ └─it
├─karaf
└─src
├─main
│ └─resources
└─site
2. 执行 mvn clean install -Dmaven.test.failure.ignore=true，成功后的信息如下：
3. 进入到 karaf.bat 目录，启动karaf
D:\\CODE\\odlexample\\example1\\example\\karaf\\target\\assembly\\bin>karaf Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256M; support was removed in 8.0 Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 Apache Karaf starting up. Press Enter to open the shell now... 100% [========================================================================] Karaf started in 32s. Bundle stats: 294 active, 294 total ________ ________ .__ .__ .__ __ \\_____ \\ ______ ____ ____ \\______ \\ _____ ___.__.| | |__| ____ | |___/ |_ / | \\\\____ \\_/ __ \\ / \\ | | \\\\__ \\< | || | | |/ ___\\| | \\ __\\ / | \\ |_> > ___/| | \\| ` \\/ __ \\\\___ || |_| / /_/ > Y \\ | \\_______ / __/ \\___ >___| /_______ (____ / ____||____/__\\___ /|___| /__| \\/|__| \\/ \\/ \\/ \\/\\/ /_____/ \\/ Hit \'<tab>\' for a list of available commands and \'[cmd] --help\' for help on a specific command. Hit \'<ctrl-d>\' or type \'system:shutdown\' or \'logout\' to shutdown OpenDaylight. opendaylight-user@root>
查看Example是否加载成功：
opendaylight-user@root>log:display | grep Example 2017-07-25 17:54:25,488 | INFO | rint Extender: 1 | ExampleProvider | 208 - org.opendaylight.example.impl - 0.1.0.SNAPSHOT | ExampleProvider Session Initiated opendaylight-user@root>
关闭OpenDaylight:
opendaylight-user@root>shutdown -f
opendaylight-user@root>
三、问题记录
[INFO] --- maven-antrun-plugin:1.8:run (move-autowire-test) @ example-features --- [INFO] Executing tasks main: [echo] Moving autowire.xml to org/opendaylight/blueprint [INFO] Executed tasks [INFO] [INFO] --- maven-surefire-plugin:2.18.1:test (default-test) @ example-features --- [INFO] Surefire report directory: D:\\CODE\\odlexample\\example1\\example\\features\\target\\surefire-reports ------------------------------------------------------- T E S T S ------------------------------------------------------- Running org.opendaylight.odlparent.featuretest.SingleFeatureTest
surefire-reports对应的报错信息为：

原有的mvn命令为：mvn clean install --Dmaven.test.skip=true，报上面的错误后，将mvn命令调整为：mvn clean install -Dmaven.test.failure.ignore=true，surefire-reports仍有报错信息(消耗一定的时间)，但最终会跳过去。
附：
-DskipTests，不执行测试用例，但编译测试用例类生成相应的class文件至target/test-classes下。
-Dmaven.test.skip=true，不执行测试用例，也不编译测试用例类。
-Dmaven.test.failure.ignore=true，即使测试出现失败用例，仍然希望能继续构建项目
