How to add dependencies to java project automatically based on the import statements?

I'm not familiar with using java package. Now I'm given a set of java files that import plenty of stuff. But there's no pom.xml file provided.

First I tried to directly compile the files, but was told com.amazonaws is not found. So I think I may need to download all the dependencies. But there are simply too many import statements so it seems not very practical to download them one by one manually.

Then I found that I may use maven. But after I tried creating this pom.xml 

<dependencies>
  <dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.11.341</version>
  </dependency>
</dependencies>

and use mvn package. I got an error telling me building failed. I thought that might be because I didn't specify all the dependencies. Is there a way to automatically pull dependencies based on import statements in the java files?

Using MVN is best approach to add dependencies to you project. You need to write some more stuff in your pom.xml . You can go through this example https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html to create a maven project step by step

Maven is the right way to go. And you've made a good start.

Although Maven is very good about pulling "implicit dependencies", it can't "guess" everything. It sounds like you're going to have to add just a bit more to your pom.xml
