Maven在本地存儲庫中找不到依賴關係

-2

看起來很簡單，所以我必須在配置時遇到一些問題。有一個示範項目與POM：Maven在本地存儲庫中找不到依賴關係

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

該項目建設，在我的.m2目錄然後，我有另外一個項目安裝正確，用POM：

當試圖從訪問類演示，我得到：

我錯過了什麼？

編輯： 很明顯，我做了演示項目mvn clean install。有趣的是，我可以使用：

javac -cp .m2/repository/com/example/demo/0.0.1-SNAPSHOT/demo-0.0.1-SNAPSHOT.jar <any java file here>

編輯： 最後MVN -X的一部分：

你有沒有在你的Maven倉庫中正確安裝Demo？如果你不確定，運行命令：mvn clean install –

編輯我的問題。是的，它按照原始問題中的說明正確安裝。 – user2669285

問題是無法找到'Aclass'類。問題在於這個類在哪裏定義？這個類'Aclass'在'com.example.Demo2Application'中被引用？ – khmarbaise

的Maven沒有找到包com。示例在此配置。

<dependency> 
    <groupId>com.example</groupId> 
    <artifactId>demo</artifactId> 
    <version>0.0.1-SNAPSHOT</version> </dependency>

所以，你必須使用命令安裝該軟件包爲本地包：MVN清潔的第一個項目安裝。

或者你也可以通過使用安裝它作爲第三方包：

MVN安裝：安裝文件-Dfile = {目錄} \ {人口統計學版本}的.jar -DgroupId =融爲一體。例如 -DartifactId =演示-Dversion = {}版本= -Dpackaging罐子

正確安裝後，它會工作。

不，如原始問題 - 演示在.m2中正確安裝 – user2669285

我以爲您使用其他帳戶來構建此項目。我看到lukasz主目錄，但下一個版本的信息是ala主目錄。請務必在正確的位置使用.m2 – ducanhng

這裏有幾點建議：

與「MVN -X淨安裝」調試運行你的破構建。日誌應該包括什麼回購。 URL Maven正在尋找每個依賴項。
解壓縮您的jar文件以驗證您想要的類是否包含在內。

運行「mvn -X clean install」爲我工作時，我嘗試過的一切都沒有。我正在使用IntelliJ，當點擊Download Sources＆Docs時，maven不會安裝hibernate-search-orm。 – Grim
