如何將本地jar添加到Maven項目

Question

我嘗試了一個小型的maven項目，然后嘗試連接到db2數據庫，因此需要com.ibm.db2.jcc.DB2Driver jar進行連接。

我嘗試了許多來自Internet的方法，但仍然失敗，這是我嘗試過的一些方法：

1. 在pom.xml中編輯

     <dependency> <groupId>com.ibm.db2</groupId> <artifactId>db2jcc4</artifactId> <version>10.5.0.7</version> <scope>system</scope> <systemPath> /home/Workspace/book/springData/lib/db2jcc4-10.5.0.7.jar </systemPath> </dependency> 

2. 使用maven命令安裝：

    mvn install:install-file -Dfile=/home/Workspace/book/springData/lib/db2jcc4-10.5.0.7.jar -DpomFile=/home/Workspace/book/springData/pom.xml 

   要么

    mvn install:install-file -Dfile=/home/meow/Workspace/mbsb-cib/springData/lib/db2jcc4-10.5.0.7.jar -DgroupId=com.ibm.db2 -DartifactId=db2jcc4 -Dversion=10.5.0.7 -Dpackaging=jar -DgeneratePom=true 

但是，我仍然無法加載JDBC驅動程序。

Answer 1

嘗試從pom.xml的中央存儲庫添加引用？

<!-- https://mvnrepository.com/artifact/com.ibm.db2.jcc/db2jcc4 -->
<dependency>
     <groupId>com.ibm.db2.jcc</groupId>
     <artifactId>db2jcc4</artifactId>
     <version>10.1</version>
</dependency>

添加后，請使用maven重建項目。
