idea maven-compiler-plugin报红

解决方案：

在<artifactId>maven-compiler-plugin</artifactId>下面加上版本<version>3.0</version>

<build>
	<finalName>test-demo</finalName>
	<plugins>
		<plugin>
			<artifactId>maven-compiler-plugin</artifactId>
			<version>3.0</version>	<!-- 加上版本号 -->
			<configuration>
				<source>1.8</source>
				<target>1.8</target>
				<encoding>utf-8</encoding>
			</configuration>
		</plugin>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<configuration>
				<mainClass>com.test.ApplicationMain</mainClass>
			</configuration>
			<executions>
				<execution>
					<goals>
						<goal>repackage</goal>
					</goals>
				</execution>
			</executions>
		</plugin>
	</plugins>
</build>
