maven知識總結

一、maven的優勢，下載，加載順序

a) 約定優於配置

b) 簡單

c) 測試支持

d) 構建簡單

e) CI

f) 插件豐富

2. 下載

a) https://maven.apache.org/download.cgi

b) 安裝

超級pom，pom的級聯關係src/main/java是在這個地方規定的

c) maven-model-builder-3.3.9.jar/org/apache/maven/model

d) 配置 MVM_HOME

i. Windows path

ii. Linux .bash_profile

iii. MAVEN_OPTS

iv. 配置setting.xml

<id>alimaven</id>

<name>aliyun maven</name>

<url>http://maven.aliyun.com/nexus/content/groups/public/</url>

<mirrorOf>central</mirrorOf>

</mirror>

<mirrorOf>central</mirrorOf>

<name>HumanReadable Name for this Mirror.</name>

<url>http://uk.maven.org/maven2/</url>

</mirror>

<mirrorOf>central</mirrorOf>

<url>http://maven.oschina.net/content/groups/public/</url>

</mirror>

<id>osc_thirdparty</id>

<mirrorOf>thirdparty</mirrorOf>

<url>http://maven.oschina.net/content/repositories/thirdparty/</url>

</mirror>

二、maven的傳遞依賴和作用域（轉載）

三、maven仲裁管理：（轉載）

https://blog.csdn.net/wanyanxgf/article/details/6617403

四、maven 生命週期 lifecycle/phase/goal

lifecycle,phase,goal以及mojo之間的作用和區別，可以參考下面這篇博客：

https://blog.csdn.net/glory1234work2115/article/details/51570073

1.A BuildLifecycle is Made Up of Phases

2.A BuildPhase is Made Up of Plugin Goals

五、版本管理

a) 1.0-SNAPSHOT

i. repository 刪除

ii. mvn cleanpackage -U (強制拉一次)

b) 主版本號.次版本號.增量版本號-<里程碑版本>

1.0.0-RELAESE

六、常用命令

a) mvn clean compile

b) mvn clean 刪除target/

c) mvn clean test test case junit/testNG

d) mvn clean package 打包

e) mvn clean install 把項目install到local repo

f) mvn deploy 發本地jar發佈到remote

七、插件

a) 常用插件

i. https://maven.apache.org/plugins/

ii. http://www.mojohaus.org/plugins.html

iii. findbugs 靜態代碼檢查

https://blog.csdn.net/Fancy_xty/article/details/51718687（idea中安裝findbug插件）

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>findbugs-maven-plugin</artifactId>
    <version>3.0.0</version>
    <configuration>
        <!-- <configLocation>${basedir}/springside-findbugs.xml</configLocation> -->
        <threshold>High</threshold>
        <effort>Default</effort>
        <findbugsXmlOutput>true</findbugsXmlOutput>
        <!-- findbugs xml輸出路徑-->
        <findbugsXmlOutputDirectory>target/site</findbugsXmlOutputDirectory>
    </configuration>
</plugin>

iv. versions 統一升級版本號

1. mvnversions:set -DnewVersion=1.1

v. source 打包源代碼（插件）

<plugin>
    <artifactId>maven-source-plugin</artifactId>
    <version>2.3</version>
    <executions>
        <execution>
            <id>attach-sources</id>
            <phase>install</phase>
            <goals>
                <goal>jar-no-fork</goal>
            </goals>
        </execution>
    </executions>
</plugin>

vi. assembly 打包zip、war

vii. tomcat7

八、自定義插件 https://maven.apache.org/guides/plugin/guide-java-plugin-development.html

參考文檔：https://blog.csdn.net/z69183787/article/details/52982249

dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-plugin-api</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>org.apache.maven.plugin-tools</groupId>
<artifactId>maven-plugin-annotations</artifactId>
<version>3.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-utils</artifactId>
<version>3.0.8</version>
</dependency>

一定要依賴這兩個jar包

a) <packaging>maven-plugin</packaging>

b) extendsAbstractMojo

d) mvn install

e) 參數傳遞

九、 Profile

a) 使用場景dev/test/pro

<profiles>
    <profile>
        <id>dev</id>
        <properties>
            <profiles.activation>dev</profiles.activation>
        </properties>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
    </profile>

    <profile>
        <id>test</id>
        <properties>
            <profiles.activation>test</profiles.activation>
        </properties>
    </profile>
    <profile>
        <id>prd</id>
        <properties>
            <profiles.activation>prd</profiles.activation>
        </properties>
    </profile></profiles>

build>
    <finalName>winner-mvn-profile</finalName>
    <resources>
        <resource>
            <directory>src/main/resources/${profiles.activation}</directory>
        </resource>
    </resources></build>

mvn install -Ptest 就是打包 test/* 即test目錄下的所有文件

具體配置，參考這個博客：http://blog.51cto.com/xiaok007/1907509

b) setting.xml 家和公司兩套

4. 倉庫

maven構建私服：https://blog.csdn.net/shenshen123jun/article/details/9084293

a) 下載

b) 安裝解壓

c) 使用http://books.sonatype.com/nexus-book/reference3/index.html

localhost:8081,賬號admin/admin123

i. http://192.168.1.6:8081/nexus

ii. admin/admin123
