maven项目打包成可执行jar

 在pom中添加

<build>
                <finalName>import_tool</finalName>
         <plugins>
            <plugin>

                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>

                        <phase>install</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.directory}/lib</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <!--直接将所有依赖一起打包-->
           <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-assembly-plugin</artifactId>  
            <version>2.5.5</version>  
            <configuration>  
                <archive>  
                    <manifest>  
                        <mainClass>com.xxx.ThreadTest</mainClass>  
                    </manifest>  
                </archive>  
                <descriptorRefs>  
                <!--打包后缀名称-->
                    <descriptorRef>jar-with-dependencies</descriptorRef>  
                </descriptorRefs>  
            </configuration>  
        </plugin>  
        </plugins>
       </build>

然后执行mvn assembly:assembly

然后会在target中出现这样一个jar

这样即为打包成功

执行  java -jar xxx.jar 即可

适用于没有普通的，没有集成相应框架的，集成框架的没有测试
