Android Studio 3.0 is failing to build with Gradle 4.2.1

android

(Jamil Rahman) #1

Hello All:
I am new with Android Studio (AS) and trying to use it with following configurations and setup. But I am getting Gradle build error. Can you please help me to resolve the issue ?

  1. AS -> Settings -> Gradle -> Project-level settings = Use local gradle wrapper (recommended)
  2. AS -> Project Structure -> Project -> Gradle version = 4.2.1
  3. AS -> Project Structure -> Project -> Android Plugin Version = 3.0.0
  4. Put all the .JAR files under app.libs folder of the AS project (my project name is AppiumTest2)

Gradle build porcess started but ended with exception (here is the stacktrace log):

/*****
D:\AppiumTools\AppiumTest2>gradlew clean --stacktrace

FAILURE: Build failed with an exception.

  • What went wrong:
    A problem occurred configuring root project ‘AppiumTest2’.

Could not resolve all files for configuration ‘:classpath’.

Hi, I have same problems! I can’t build my project anymore!!!


(Jamil Rahman) #3

Hi Alexei, now I am feeling am not alone. Let’s see if some one brings light in our darkness.


(towa) #4

I had similar problem.
And my problem has been resolved by the workaround of the following link.

Would you see this?

Solutions for “Unable to resolve dependency” on building with Android Studio 3.0


(Jamil Rahman) #5

Tohosokawa san,
Thanks for your hint of resolution. I’ll try the same as you suggested and let you know.
Best Regards.

Jamil, Ottawa, Canada.


(Jamil Rahman) #6

Hello Tohosokawa san, Your solution couldn’t be verified because, we are NOT using any proxy server.


(Stefan Oehme) #7

You might be affected by a problem in JDK 9, which shipped with an empty trust store at least in some versions. See https://mobile.twitter.com/CedricChampeau/status/913679310896156672


(towa) #8

Your log messages seem to “Error Messages 2” at the web site.
The cause of “Error Messages 2” is SSL certification.
And the solution is not related proxy.

Cloud you see “Error Messages 2” and solution?

“Error Messages 1” and “Error Messages 2” have no relations.

Unlikely, as the information you posted says that you couldn’t download https://dl.google.com/dl/android/maven2/com/android/support/appcompat-v7/26.0.0-beta1/appcompat-v7-26.0.0-beta1.pom, which is a valid, working URL. You haven’t provided anything that would help someone determine why your build can’t access that file beyond what is already mentioned in the thread.
