将Maven项目打包成可执行jar文件(引用第三方jar)

水深无声 2021-05-27 20:38 589阅读 0赞

方法一. mvn assembly 或 mvn package (一个jar包)

把依赖包和自己项目的文件打包如同一个jar包(这种方式对spring的项目不支持)

<build>  
          <plugins>  
              <plugin>  
                  <artifactId>maven-assembly-plugin</artifactId>  
                  <configuration>  
                      <archive>  
                          <manifest>  
                              <mainClass>com.tang.CSVUtils</mainClass>  
                          </manifest>  
                      </archive>  
                      <descriptorRefs>  
                          <descriptorRef>  
                              jar-with-dependencies  
                          </descriptorRef>  
                      </descriptorRefs>  
                  </configuration>  
                    
                    
              </plugin>  
          </plugins>  
      </build>

Eclipse 中 Run As--- Maven clean ---Maven assembly:assembly（或 Maven package）

Target目录生成如下文件：

![20150822110450932][]

其中，

testLog4j-0.1.jar 是不可直接运行的，因为没有带第三方包。

testLog4j-0.1-jar-with-dependencies.jar 就是带有第三方包的可执行 jar 包，

在命令行执行 [Java][] -jar testLog4j-0.1-jar-with-dependencies.jar 即可运行

方法二：mvn package(一个jar包和一个lib文件夹)

<build>  
        <plugins>  
            <plugin>  
                <groupId>org.apache.maven.plugins</groupId>  
                <artifactId>maven-jar-plugin</artifactId>  
                <version>2.4</version>  
                <configuration>  
                    <archive>  
                        <manifest>  
                            <addClasspath>true</addClasspath>  
                            <classpathPrefix>lib/</classpathPrefix>  
                            <mainClass>com.tang.CSVUtils</mainClass>  
                        </manifest>  
                    </archive>  
                </configuration>  
            </plugin>  
            <plugin>  
                <groupId>org.apache.maven.plugins</groupId>  
                <artifactId>maven-dependency-plugin</artifactId>  
                <executions>  
                    <execution>  
                        <id>copy</id>  
                        <phase>package</phase>  
                        <goals>  
                            <goal>copy-dependencies</goal>  
                        </goals>  
                        <configuration>  
                            <outputDirectory>${project.build.directory}/lib</outputDirectory>  
                        </configuration>  
                    </execution>  
                </executions>  
            </plugin>  
        </plugins>  
    </build>

执行maven package 进行打包进入target目录。

其中lib就是第三方jar包的目录，在其他项目引入testLog4j-0.1.jar会自动找到并引入lib里面的包.

只需要拷贝这两个（lib和testLog4j-0.1.jar）即可放到其他地方用了。

在命令行执行：java -jar testLog4j-0.1.jar

方法三：mvn package(推荐)(一个zip包，里面有一个jar包，一个lib文件夹，和一个conf文件夹)

(1)conf/package.xml (conf 文件夹和pom.xml在同一级目录)

<assembly>    
        <id>bin</id>    
            
        <formats>    
            <format>zip</format>    
        </formats>    
        
            
        <dependencySets>    
            <dependencySet>    
                    
                <useProjectArtifact>false</useProjectArtifact>    
                <outputDirectory>lib</outputDirectory>    
                <unpack>false</unpack>    
            </dependencySet>    
        </dependencySets>    
        
        <fileSets>    
                
            <fileSet>    
                <directory>${project.basedir}</directory>    
                <outputDirectory>/</outputDirectory>

                    <include>README*</include>    
                    <include>LICENSE*</include>    
                    <include>NOTICE*</include>

            <fileSet>    
                <directory>${project.basedir}\conf</directory>    
                <outputDirectory>conf</outputDirectory>    
                <includes>    
                    <include>*.xml</include>    
                    <include>*.properties</include>  
                    <include>*.key</include>   
                </includes>    
            </fileSet>    
                
                
            <fileSet>    
                <directory>${project.build.scriptSourceDirectory}</directory>    
                <outputDirectory></outputDirectory>    
                <includes>    
                    <include>startup.*</include>    
                </includes>    
            </fileSet>    
        
                
            <fileSet>    
                <directory>${project.build.directory}</directory>    
                <outputDirectory></outputDirectory>    
                <includes>    
                    <include>*.jar</include>    
                </includes>    
            </fileSet>    
        </fileSets>    
    </assembly>

(2)pom.xml

<build>    
          <plugins>  
            <plugin>  
                  <groupId>org.apache.maven.plugins</groupId>  
                  <artifactId>maven-compiler-plugin</artifactId>  
                  <version>3.1</version>  
                  <configuration>  
                      <compilerVersion>1.6</compilerVersion>  
                      <source>1.6</source>  
                      <target>1.6</target>  
                  </configuration>  
             </plugin>    
                  
            <plugin>    
                <groupId>org.apache.maven.plugins</groupId>    
                <artifactId>maven-jar-plugin</artifactId>    
                <version>2.4</version>    
                    
                <configuration>    
                        
                    <archive>    
        
                            
                        <addMavenDescriptor>false</addMavenDescriptor>    
        
                            
                        <manifest>    
                          
                                
                            <addClasspath>true</addClasspath>    
                                
                            <classpathPrefix>lib/</classpathPrefix>    
                                
                            <mainClass>com.tang.your-Main-class</mainClass>    
                        </manifest>    
                    </archive>    
                        
                    <excludes>    
                        <exclude>${project.basedir}/xml/*</exclude>    
                    </excludes>    
                </configuration>    
            </plugin>    
        
                
            <plugin>    
                <groupId>org.apache.maven.plugins</groupId>    
                <artifactId>maven-assembly-plugin</artifactId>    
                <version>2.4</version>    
                    
                <configuration>    
                        
                    <descriptors>    
                        <descriptor>conf/package.xml</descriptor>    
                    </descriptors>    
                </configuration>    
                <executions>    
                    <execution>    
                        <id>make-assembly</id>    
                        <phase>package</phase>    
                        <goals>    
                            <goal>single</goal>    
                        </goals>    
                    </execution>    
                </executions>    
            </plugin>     
          </plugins>    
      </build>

mvn install后，此时会在target目录下生成一个zip文件，如：

youArtifactId-0.0.1-bin.zip 解压后有：

conf 文件夹， lib文件夹，  youArtifactId-0.0.1-bin.jar
