PandaMonkey updated IGNITE-7799:
--------------------------------
    Description: 
Hi, by analyzing ignite-master\modules\aws\pom.xml, I found that there are two 
versions of *org.apache.httpcomponents:httpclient*. Their introduced path is:
 # 
org.apache.ignite:ignite-aws:2.5.0-SNAPSHOT::null->com.amazonaws:aws-java-sdk-core:1.11.75::compile->org.apache.httpcomponents:httpclient:4.5.2::compile
 # 
org.apache.ignite:ignite-aws:2.5.0-SNAPSHOT::null->org.apache.httpcomponents:httpclient:4.5.1::compile

Of them, httpclient:4.5.2 is the transitive dependency, and httpclient:4.5.1 is 
the direct dependency. By further analyzing the source code, we found they have 
different features.

Maven provides the version arbitration mechanism-----"nearest wins", and then 
your project will explicitly use the older version: httpclient:4.5.1. However, 
Maven doesn't know which version is actual required by your project. 

If ignite depends on the methods of com.amazonaws:aws-java-sdk-core, at the 
same time, those invoked methods need the features definded in 
httpclient:4.5.2. The dependency conflict problem will appear.

The dependency conflict problem brings high risks of "*NotClassDefFoundError:*" 
or "*NoSuchMethodError*" issues at runtime. Please notice this problem. *The 
solution is upgrading httpclient from 4.5.1 to 4.5.2.*

Maven provides the version arbitration mechanism-----"nearest wins", and then 
your project will explicitly use the older version: httpclient:4.5.1. The 
problem will arise when Ignite uses the methods defined in the transitive JAR 
httpclient 4.5.2, and those required methods don't exist in the loaded version 
httpclient:4.5.1.

The dependency conflict problem brings high risks of "*NotClassDefFoundError:*" 
or "*NoSuchMethodError*" issues at runtime. Please notice this problem. *The 
solution is upgrading httpclient from 4.5.1 to 4.5.2.*
