您可以尝试在pom中直接使用插件，例如：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <testSource>1.8</testSource>
                <testTarget>1.8</testTarget>
                <compilerArgument>-Xlint:deprecation</compilerArgument>
            </configuration>
        </plugin>
    </plugins>
</build>
