问题
Just after updating Android studio 3.0 yesterday from 2.3.3 version, I am facing issue related to DexMergerException.
Someone else also posted question-related to this. But in this question, I want to analyze the stack trace to find the related solution(since i am newbiew here..).
I am unable to resolve it even after excluding group that might be using it. Since I am not aware of which component colliding with HttpCore so I'd use this code to exclude httpCore:
implementation ('com.android.volley:volley:1.0.0') {
exclude group: 'org.apache.httpcomponents'
}
Please check the Terminal logcat that would be useful to figure out the root issue:
D:\Office_Work\Android\MnE App>gradlew build --stacktrace

I just need a little hint to find out which component to exclude in gradle file.
Thanks.
回答1:
After looking for a lot of options around the internet. I figured out to include a configuration tag inside build.gradle to exclude HttpCore :
configurations {
all*.exclude group: 'org.apache.httpcomponents', module:'httpclient'
}
Hope it will help others.
Thanks.
