在 spring 启动 maven 项目中与第三方 jar 的编译错误

Question

I have a spring boot project in Eclipse. I have added an external 3rd party jar in project build path which is not a maven dependency. Now I am able to import 2 classes from the jar that I need and I wrote my some implementation. Now when i am trying to build my maven project with clean install , I am getting compilation failure with the same 2 imports that I have used. The error says: package does not exist.

Am I missing anything in the configuration part? I have added the jar as external jar in project build path. Then I have clean compiled the project. is there anything else that i need to do to use a 3 rd party jar in a spring boot project which is build by maven?

Answer 1

You must add this external jar as a dependency to make the maven build work.

There is a system scope for that purpose. Example:

<dependency>
  <groupId>javax.sql</groupId>
  <artifactId>jdbc-stdext</artifactId>
  <version>2.0</version>
  <scope>system</scope>
  <systemPath><path_to_jar>/your.jar</systemPath>
</dependency>

Answer 2

First add a local repo like below:

    <repository>
        <id>in-project</id>
        <name>Local Project Repo</name>
        <url>file:///${project.basedir}/lib/</url>
    </repository>

Then add the dependency as below:

    <dependency>
        <groupId>abcd</groupId>
        <artifactId>efgh</artifactId>
        <version>1.X.O</version>
    </dependency>
