Here is error at the time of maven install-

[INFO] Scanning for projects...
[WARNING] The POM for com.mavenDemo:AirportServices:jar:0.0.1-SNAPSHOT is missing, no dependency information available
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[ERROR] Failed to execute goal on project AirportWeb: Could not resolve dependencies for project com.mavenDemo:AirportWeb:war:0.0.1-SNAPSHOT: Could not find artifact com.mavenDemo:AirportServices:jar:0.0.1-SNAPSHOT ->

I have already added all the dependency what is the issue in this code.

Answer 1

关于错误消息

[ERROR] Failed to execute goal on project AirportWeb: 
    Could not resolve dependencies for project 
    com.mavenDemo:AirportWeb:war:0.0.1-SNAPSHOT: 
    Could not find artifact com.mavenDemo:AirportServices:jar:0.0.1-SNAPSHOT

以及显示我们在 AirportWeb 目录中执行 mvn install 的注释。

那么正确的位置应该是父项目目录，AirportSys。因为它是所有子模块的父模块。 Maven 会将其与这些子模块一起安装，并使它们在我们的本地存储库中可用。
