Might be something obvious, but this issue got me stuck for a while.

Some of the libraries require com.google.guava:guava:21.0 as the dependency, however gradle fails to fetch it from the maven repository. it's a legacy project, so versions are not the latest.

Error log:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find guava-21.0-cdi1.0.jar (com.google.guava:guava:21.0).
     Searched in the following locations:
         https://repo.maven.apache.org/maven2/com/google/guava/guava/21.0/guava-21.0-cdi1.0.jar

guava-21.0.jar (without -cdi1.0 suffix) exists on that path. Why does gradle ads the -cdi1.0 suffix to the filename and is it possible to disable this feature? or i simply misunderstanding something and there is something else in play?

i tried to specify guava dep separately compile(group: 'com.google.guava', name: 'guava', version: '21.0'), however it doesn't affect anything.

build.gradle: (generated by gradle init from maven pom.xml)

plugins {
    id 'java'
    id 'maven-publish'
}

repositories {
    mavenCentral()
    maven {

    }

    ... etc other deps
}

        }
    }

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

The cdi-1.0 suffix is a classifier, usually seen in a pom like: <classifier>cdi1.0</classifier>. As far as I can see, it's really only in Guava 15, so I would check everywhere to try to find the offender. Some things to try:

  • Check transitive dependencies. Use gradle dependencies to look for what is trying to pull in com.google.guava:guava:21.0 and the incorrect classifier. Maybe one of those is doing so incorrectly and you can try changing versions or forcing something different. Hopefully forcing doesn't cause too much trouble with the classifier. Time permitting, you could try to find the dependency poms that might be mismatched.
  • Restart / Invalidate Caches in your IDE, as well as clearing Gradle cache.

  • yep, i did all of those - checked dep tree, it is resolved to `com.google.guava:guava:21.0-jre` , without `cdi` classifier, cleared gradle and IDE caches, tried to update all deps, still failing on `guava` with `cdi` – user1935987 Jan 29 '21 at 13:55
  • also tried to use `force` and `strictly`, but it doesn't seem to impact the usage of `cdi` classifier – user1935987 Jan 29 '21 at 14:09
