maven打包時加入依賴包及加入本地依賴包 - shanheyongmu－IT工程師數位筆記本

maven打包的時候默認是不加入依賴的jar包的，所以想打出一個獨立的可運行jar包的話直接mvn clean install package是不行的。需要略改動下pom文件，加入如下plugin

<build>
        <sourceDirectory>src/main/java</sourceDirectory>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <defaultLibBundleDir>lib</defaultLibBundleDir>
                    <source>1.5</source>
                    <target>1.5</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathPrefix></classpathPrefix>
                            <mainClass>com.xx.xx.xx</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy</id>
                        <phase>install</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>
                                ${project.build.directory}
                            </outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

maven打包的時候有些jar包是不在mavencenter的。需要在pom中引入相關的本地jar包，那么相關的depency應該像如下更改

 <dependency>
        <groupId>org.wltea.ik-analyzer</groupId>
        <artifactId>ik-analyzer</artifactId>
        <version>3.2.8</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/lib/ik-analyzer-3.2.8.jar</systemPath>
    </dependency>

對于war包系統來說，有時候需要把jar包打到相關的war包中，可以使用plugin，默認將lib下的所有jar文件打包到WEB-INF/lib下。當然也是可以打包其他的文件的，諸如xml,properties等的。相關的plugin如下：

 <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.3</version>
            <configuration>
                <warName>${project.artifactId}</warName>
                <webResources>
                    <resource>
                        <directory>lib/</directory>
                        <targetPath>WEB-INF/lib</targetPath>
                        <includes>
                            <include>**/*.jar</include>
                        </includes>
                    </resource>
                </webResources>
            </configuration>
        </plugin>
