Maven 之setting.xml pom.xml

1)、 配置Maven 从私服上下载构件

a、在POM.xml文件中配置

[html] view plain copy

1. <repositories>  
2.     <repository>  
3.         <id>central.maven.com</id>  
4.         <name>mapbar central mirror.</name>  
5.         <url>http://192.168.1.252:8081/nexus/content/repositories/central/</url>  
6.     </repository>  
7.     <repository>  
8.         <id>3rd.mapbar.com</id>  
9.         <name>mapbar thirdparty central mirror.</name>  
10.         <url>http://192.168.1.252:8081/nexus/content/repositories/thirdparty/</url>  
11.     </repository>  
12.     <repository>  
13.         <id>public.mapbar.com</id>  
14.         <name>mapbar tech API maven mirror.</name>  
15.         <url>http://192.168.1.252:8081/nexus/content/groups/public/</url>  
16.     </repository>  
17.     <repository>  
18.         <id>releases.mapbar.com</id>  
19.         <name>mapbar thirdparty central mirror.</name>  
20.         <url>http://192.168.1.252:8081/nexus/content/repositories/releases/</url>  
21.     </repository>  
22. </repositories>  

这样的配置只对Maven项目有效，在实际引用中，我们想通过一次配置就能让本机所有的Maven项目都能使用自己的Maven私服。这个时候就要用settings.xml 文件。改文件对本机所有的Maven项目有效。配置如下:

[html] view plain copy

1. <profiles>  
2.     <profile>  
3.         <id>nexus</id>  
4.         <repositories>  
5.             <repository>  
6.                 <id>nexus</id>  
7.                 <name>Nexus</name>  
8.                 <url>http://192.168.53.55:8081/nexus/content/groups/public/</url>  
9.                 <releases>  
10.                     <enabled>true</enabled>  
11.                 </releases>  
12.                 <snapshots>  
13.                     <enabled>true</enabled>  
14.                 </snapshots>  
15.             </repository>  
16.         </repositories>  
17.         <pluginRepositories>  
18.             <pluginRepository>  
19.                 <id>nexus</id>  
20.                 <name>Nexus</name>  
21.                 <url>http://192.168.53.55:8081/nexus/content/groups/public/</url>  
22.                 <releases>  
23.                     <enabled>true</enabled>  
24.                 </releases>  
25.                 <snapshots>  
26.                     <enabled>true</enabled>  
27.                 </snapshots>  
28.             </pluginRepository>  
29.         </pluginRepositories>  
30.     </profile>  
31. </profiles>  
32. <activeProfiles>  
33.     <activeProfile>nexus</activeProfile>  
34. </activeProfiles>  

2)、配置自动发布构件到私服

POM.XML 配置：

[html] view plain copy

1. <distributionManagement>  
2.       <repository>  
3.         <id>releases</id>  
4.         <url>http://localhost:8081/nexus/content/repositories/thirdparty/</url>  
5.       </repository>  
6. </distributionManagement>  

在命令行键入：mavn  deploy 则构件自动发布到本地和上传到私服 http://localhost:8081/nexus/content/repositories/thirdparty 这个目录下

需要注意2点：

1、发布的版本类型必须和nexus里的Policy类型一致。

2、setting.xml 文件必须配置servers，其中id必须和repository下的id一致。

[html] view plain copy

1. <servers>  
2.         <server>  
3.             <id>releases</id>  
4.             <username>admin</username>  
5.             <password>admin123</password>  
6.         </server>  
7.         <server>  
8.             <id>snapshots</id>  
9.             <username>admin</username>  
10.             <password>admin123</password>  
11.         </server>  
12.         <server>  
13.             <id>deploymentRepo</id>  
14.             <username>admin</username>  
15.             <password>admin123</password>  
16.         </server>  
17.     </servers>  

3)、在<build> 中配置项目构建信息，生成doc,source  

[html] view plain copy

1. <!-- 项目的构建信息 -->  
2.     <build>  
3.             <plugins>  
4.             <!-- generate a javasource -->  
5.             <plugin>  
6.                 <groupId>org.apache.maven.plugins</groupId>  
7.                 <artifactId>maven-source-plugin</artifactId>  
8.                 <executions>  
9.                     <execution>  
10.                         <id>attach-sources</id>  
11.                         <goals>  
12.                             <goal>jar</goal>  
13.                         </goals>  
14.                     </execution>  
15.                 </executions>  
16.             </plugin>  
17.             <!-- generate a javadoc -->  
18.             <plugin>  
19.                 <groupId>org.apache.maven.plugins</groupId>  
20.                 <artifactId>maven-javadoc-plugin</artifactId>  
21.                 <executions>  
22.                     <execution>  
23.                         <id>attach-javadocs</id>  
24.                         <goals>  
25.                             <goal>jar</goal>  
26.                         </goals>  
27.                     </execution>  
28.                 </executions>  
29.             </plugin>  
30.         </plugins>  
31.     </build>  

输入命令：mvn install

 在target目录下生成了

MavenTest-0.0.1-release.jar           --.class文件

MavenTest-0.0.1-release-sources.jar    --.java 文件

MavenTest-0.0.1-release-javadoc.jar   --doc 文件
