如何将.jar文件添加到IntelliJ IDEA Java项目中？

Question

I have a java project loaded into IntelliJ IDEA. The code requires JDBC and so I downloaded and unzipped the sqljdbc_6.4.0.0_enu file into the recommended directory, "C:\\Program Files\\Microsoft JDBC Driver 6.4 for SQL Server". This creates the jar files:

• mssql-jdbc-6.4.0.jre7.jar
• mssql-jdbc-6.4.0.jre8.jar
• mssql-jdbc-6.4.0.jre9.jar

in the directory, "C:\\Program Files\\Microsoft JDBC Driver 6.4 for SQL Server\\sqljdbc_6.4\\enu". And so, now, how do I make use of all this in my project in IntelliJ IDEA? And if I later put all my java code into Git Hub, how can I ensure that another user will have code that will compile and link? Will I have to include the .jar file in Git Hub somehow?

Answer 1

you should not do this. For your case, you can choose one of them:

1. create lib foder into project folder - put .jar files in the folder- setup module with library point to the folder - commit metadata folder of IDEA such as .idea, {projectName}.iml (not recommend)

2. The best solution is using maven or Gradle, you are able to put the dependencies which are neccessary into pom.xml file. (Recommend)

Answer 2

You can refer this for adding external jar files in IntelliJ IDEA.

As for GitHub, you can put your jar files there by removing *.jar from .gitignore configuration file. However this is not a recommended practice to have JAR files in repository as they've considerable size. You can consider using some build tool(maven or gradle) to add external dependencies.
