Where can I download the jar for org.apache.http package?
At the Maven repo, there are samples to add the dependency in maven, sbt, gradle, etc.
https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore/4.4.11
ie for Maven, you just create a project, for example
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
then look at the pom.xml, then at the library at the dependencies xml element:
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpcore</artifactId> <version>4.4.11</version></dependency>
For sbt do something like
sbt new scala/hello-world.g8
then edit the build.sbt to add the library
libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"
