Windows Gradle build : Could not expand ZIP

Question

I'm working on a MapReduce app and currently using Gradle to build the project. I'm using following dependencies and when I execute the ./gradlew clean build I'm getting Could not expand ZIP error.

implementation 'org.apache.hive:hive-jdbc:3.1.3'
implementation 'org.apache.hadoop:hadoop-common:3.3.2'
implementation 'org.apache.hadoop:hadoop-hdfs:3.3.2'

Stacktrace

I tried clearing out gradle cache gradlew cleanBuildCache --refresh-dependencies that didn't workout.

Answer 1

I was able to figure out the issue. My goal was to create a fatjar and for that I have updated the gradle jar task to create a fat jar.

jar {
    manifest {
        attributes "Main-Class": "main.Main"
    }
    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
    duplicatesStrategy = DuplicatesStrategy.INCLUDE
}

The issue was, in the C:\Users\..\.gradle\cache\.. folder there were some dependencies without a .jar file. In my case only a .pom file. So I removed the task and created a new task(customFatJar) only to get .jar files. That fixed the issue.

Fix:

task customFatJar(type: Jar) {
    manifest {
        attributes 'Main-Class': 'main.Main'
    }
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE
    from {
        configurations.runtimeClasspath.filter {
            it.name.endsWith('.jar')
        }
    }
    with jar
}
