To manage your dependencies use tools like Maven, Gradle or Ant + Ivy. Those will make your life a whole lot easier, the dependencies will be managed and you will get also all transitive dependencies (the dependencies the framework you use depends on). This will save you a lot of searching around the internet.

With either of these tools you create a build file (ant and maven use XML, Gralde uses Groovy for that) and express your dependencies.

For example this build file for gradle, build.gradle will create a jar and use all the dependencies.

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.springframework', name: 'spring-context', version: '3.2.5.RELEASE'        
    compile group: 'org.springframework', name: 'spring-context-support', version: '3.2.5.RELEASE'        
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

This gradle.build will add the needed spring jars and the dependencies it needs for that.
