p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; text-align: justify; font: 12.0px "Helvetica Neue"; color: #454545 }
span.s1 { font: 12.0px ".PingFang SC" }

1,设置编译版本为jdk 1.8

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
    </plugins>
</build>

2 maven排除依赖jar包中的子jar

<dependency>?
<groupId>com.xx.xx</groupId>?
<artifactId>xx</artifactId>?
<version>${xx.version}</version>?
<exclusions>?
<exclusion>?
<groupId>org.springframework</groupId>?
 <artifactId>*</artifactId>?
</exclusion>?</exclusions>
</dependency>

3，将maven将java项目依赖包一起打入一个jar包内需要的配置

 <plugin>
           <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                          <mainClass></mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
             </executions>
</plugin>   

打包的命令: 在项目的目录下的命令行输入：mvn clean package
