maven倉庫は手動で地元jar経典の方法をインストールして、問題の解決方法と出会います。

によると、java開発の過程で、よくあるカバンはmaven倉庫でダウンロードできない問題があります。ojdbc、saxonなどのように、手動で現地jarカバンをmaven倉庫に設置して、pom依存の問題を解決する必要があります。

メソッド**maven追加ローカルパケットコマンドmvn install:install-file**

mavenローカルインストールxml 2 j
mvn install：install-file-Dfile=xml 2 j.jar-DgroupId=comp.xml 2 j-DartifactId=xml 2 j-core-Dversion=2.5.0-Dpackaging=jar

mvn install:install-file           
-Dfile       jar 
-DgroupId     
-DartifactId       jar    
-Dversion          
-Dpackaging     

問題と解決方法*3.1ローカルパッケージはディレクトリ無効に遭遇しました。＊
