Maven配置源代码和资源目录1、配置单个源代码和资源目录2、配置多个源代码目录

<build>
	<!--默认源代码目录 -->
	<sourceDirectory>src</sourceDirectory>
	<outputDirectory>${project.build.directory}/classes</outputDirectory> <!-- ${project.build.directory}就是我们通常看到的target目录 -->
	<!--默认测试源代码目录 -->
	<testSourceDirectory>test </testSourceDirectory>
	<testOutputDirectory>${project.build.directory}/test-classes
	</testOutputDirectory>
	<!--默认资源目录 -->
	<resources>
		<resource>
			<directory>src</directory>
			<excludes>
				<exclude>**/*.java</exclude>
			</excludes>
		</resource>
	</resources>
	<!--默认测试资源目录 -->
	<testResources>
		<testResource>
			<directory>test</directory>
			<excludes>
				<exclude>**/*.java</exclude>
			</excludes>
		</testResource>
	</testResources>
