  pom.xml

Is there any way by that add all jar at a time.

Answer 1

Maven manages dependencies rather different than just including jars.

Essentially if you have a dependency on A and A uses B, you will need to have both A+B in your lib folder, but only A in your maven project, because maven transitively will include the subdependencies.

You should probably look through the maven repository, and see if you can find the jar files there in a similar version, and include that instead.

i.e. if you have commons-collections4-4.0.jar, use http://search.maven.org and write commons-collections4, and you will see a list of candidates. probably some with multiple version. Note, maven uses a groupId to scope jar files, so pick one with a suitable groupId, in this case org.apache.commons (Since commons-collections is an apache.org project).

When you have identified your dependency, it will show you ways to include it in your build, e.g. for maven, it would be

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-collections4</artifactId>
    <version>4.0</version>
</dependency>

Looking at the pom file, you will be able to spot potential subdependencies, but otherwise, once you have added the dependency to your <dependencies/> section of your pom, run a mvn dependency:tree or mvn dependency:list to see how dependencies are transitively included.

Should you end up with libraries you cannot find in maven central, read this guide for the rest http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
