给出java中的以下代码,在编译时你有很多错误:
Main.java:1:错误:包com.google.common.base不存在导入com.google.common.base.Preconditions; ^
Main.java:2:错误:包com.google.common.collect不存在导入com.google.common.collect.Lists; ^
Main.java:3:错误:包org.ros.exception不存在import org.ros.exception.RosRuntimeException; ^
Main.java:4:错误:包org.ros.internal.loader不存在import org.ros.internal.loader.CommandLineLoader; ^
Main.java:5:错误:包org.ros.node不存在import org.ros.node.DefaultNodeMainExecutor; ^
Main.java:6:错误:包org.ros.node不存在import org.ros.node.NodeConfiguration; ^
Main.java:7:错误:包org.ros.node不存在import org.ros.node.NodeMainExecutor;
我通过IntelliJ运行它.有谁知道为什么它不起作用？
