無法在AirportWeb項目上執行目標

Question

我在安裝Maven時遇到問題。 這是我的父POM文件AirportSys / pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

這是Maven安裝時的錯誤-

[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 ->

我已經添加了所有依賴關系，此代碼中的問題是什么。

Answer 1

關於錯誤消息為

[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

以及在AirportWeb目錄中執行mvn install時向我們顯示的注釋。

然后，正確的位置應該是父項目目錄AirportSys 。 由於它是所有子模塊的父級。 Maven會將其與這些子模塊一起安裝，並使其在我們的本地存儲庫中可用。
