Maven学习笔记(六) 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

<repositories>
    <repository>
        <id>central.maven.com</id>
        <name>mapbar central mirror.</name>
        <url>http://192.168.1.252:8081/nexus/content/repositories/central/</url>
    </repository>
    <repository>
        <id>3rd.mapbar.com</id>
        <name>mapbar thirdparty central mirror.</name>
        <url>http://192.168.1.252:8081/nexus/content/repositories/thirdparty/</url>
    </repository>
    <repository>
        <id>public.mapbar.com</id>
        <name>mapbar tech API maven mirror.</name>
        <url>http://192.168.1.252:8081/nexus/content/groups/public/</url>
    </repository>
    <repository>
        <id>releases.mapbar.com</id>
        <name>mapbar thirdparty central mirror.</name>
        <url>http://192.168.1.252:8081/nexus/content/repositories/releases/</url>
    </repository>
</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:

<profiles>
    <profile>
        <id>nexus</id>
        <repositories>
            <repository>
                <id>nexus</id>
                <name>Nexus</name>
                <url>http://192.168.53.55:8081/nexus/content/groups/public/</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>nexus</id>
                <name>Nexus</name>
                <url>http://192.168.53.55:8081/nexus/content/groups/public/</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </pluginRepository>
        </pluginRepositories>
    </profile>
</profiles>
<activeProfiles>
    <activeProfile>nexus</activeProfile>
</activeProfiles>

2)、配置自动发布构件到私服

POM.XML 配置：

<distributionManagement>
      <repository>
        <id>releases</id>
        <url>http://localhost:8081/nexus/content/repositories/thirdparty/</url>
      </repository>
</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。

<servers>
        <server>
            <id>releases</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
        <server>
            <id>snapshots</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
        <server>
            <id>deploymentRepo</id>
            <username>admin</username>
            <password>admin123</password>
        </server>
    </servers>

 

3)、在<build> 中配置项目构建信息，生成doc,source  

<!-- 项目的构建信息 -->
    <build>
            <plugins>
            <!-- generate a javasource -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-source-plugin</artifactId>
                <executions>
                    <execution>
                        <id>attach-sources</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <!-- generate a javadoc -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-javadoc-plugin</artifactId>
                <executions>
                    <execution>
                        <id>attach-javadocs</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </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
