Could not download org.springframework.vault - spring

Question

I am importing the gradle project in eclipse which is the spring boot application. I could see all the dependency jars are downloaded except "org.springframework.vault".
I could download the spring-vault-core-2.0.1.RELEASE.pom file from browser, so no network issues i guess.
When i checked in D:\softwares\gradle-4.6-bin\gradle-4.6\caches\modules-2\files-2.1 i could not find this directory. I tried to create this directory but i got the error pop up says "folder/file in it is open in other program". I have restarted the pc, also killed all the java process and tried to create this dir, but still failed.
I deleted the cache directory itself and did gradle build, it downloaded the jars freshly except the mentioned one.
code cannot be shared as it is working project.
when i ran the application getting the error
FAILURE: Build failed with an exception.
What went wrong:
