Cannot resolve plugin org.apache.maven.plugins:maven-source-plugin:＜unknown＞

导入项目时maven打包插件报错：

Cannot resolve plugin org.apache.maven.plugins:maven-source-plugin:

解决方案为：

在项目pom文件中指定你本地maven库中存在的maven-compiler-plugin的jar包的版本

    <build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-source-plugin</artifactId>
				<version>3.2.1</version>
				<executions>
					<execution>
						<phase>compile</phase>
						<goals>
							<goal>jar-no-fork</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
