pom.xml配置

1、使用eclipse编译

<!-- Eclipse编译代码时，使用的是自带的JDT（Java Development Tools），
        而Maven默认使用的是JAVA_HONE中的javac，而javac相对JDT的检查机制来说，
        更加的严格，所以导致Eclipse可以编译通过，而用Maven编译会报错的结果。-->

<build>
...
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<compilerId>eclipse</compilerId>
</configuration>
<dependencies>

<artifactId>plexus-compiler-eclipse</artifactId>
<version>2.2</version>
</dependency>

</plugin>
....

</build>

2、使用javac

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.5.1</version>
    <configuration>
        <source>${jdk.version}</source>
        <target>${jdk.version}</target>
        <encoding>UTF-8</encoding><!--解决GBK映射报错问题-->
        <compilerId>javac</compilerId>
    </configuration>
    <dependencies>
        <dependency>
            <!--<groupId>org.codehaus.plexus</groupId>
            <artifactId>plexus-compiler-eclipse</artifactId>
            <version>2.2</version>-->
            <groupId>org.codehaus.plexus</groupId>
            <artifactId>plexus-compiler-javac</artifactId>
            <version>2.8</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.codehaus.plexus/plexus-compiler-api -->
        <dependency>
