The SingleProjectIntegrationTest#testBuild_dockerClient test is getting stuck indefinitely with no progress:

I'm able to reproduce this locally as well with ./gradlew :jib-gradle-plugin:integrationTest --tests com.google.cloud.tools.jib.gradle.SingleProjectIntegrationTest.testBuild_dockerClient.

Where is it getting stuck?

It gets stuck at this line: https://github.com/GoogleContainerTools/jib/blob/ff15988e5eb36c686e7db47abb31bdc15c88f44a/jib-core/src/main/java/com/google/cloud/tools/jib/docker/CliDockerClient.java#L196

Other Observations

• The process appears to be blocked waiting for a result to be returned from the docker info process. Interestingly, calling just CliDockerClient#info() in the test isn't resulting in the same issue. It is only when we call ./gradlew jibDockerBuild that we run into the test method getting stuck indefinitely.

• We are also running into the same issue when reading the input from a different process (e.g. docker inspect)
