NPE when replying "N" to report operation to Liquibase Hub

[ilopmar]

Environment

Liquibase Version: 4.3.1

Liquibase Integration & Version: Micronaut

Liquibase Extension(s) & Version: N/A

Database Vendor & Version: All

Operating System Type & Version: Linux Mint 20.1

Description

I've tried to upgrade the Micronaut integration to Liquibase 4.3.1 (from 4.2.2) and when I start an application I see now a question:

14:35:11.342 [main] DEBUG liquibase.ui - A system console was detected for user input
14:35:11.342 [main] DEBUG liquibase.ui - To override or validate the auto-detected environment for user input, set the liquibase.headless property in liquibase.properties file.
Do you want to see this operation's report in Liquibase Hub, which improves team collaboration? 
If so, enter your email. If not, enter [N] to no longer be prompted, or [S] to skip for now, but ask again next time (default "S"):

If I answer "N" to that question there is a NPE.

The error doesn't happen when answering "Y" to the question.

Steps To Reproduce

• git clone https://github.com/micronaut-graal-tests/micronaut-liquibase-graal
• cd micronaut-liquibase-graal
• git checkout liquibase-npe
• ./gradlew assemble
• java -jar build/libs/micronaut-liquibase-graal-0.1-all.jar
• Answer "N" to the question.

Actual Behavior

The is a NPE:

Expected/Desired Behavior

It should work.

Additional Context

I've tried to workaround this problem by creating the file src/main/resources/liquibase.properties with content liquibase.headless=true but it is not working. I've also tried setting the LIQUIBASE_HEADLESS environment variable but that doesn't work either. What am I missing here?

Liquibase Internal QA Requirements

• Validate issue reproduces on broken build.
• Manually verify fix addresses the NPE.
• Verify all automated functional tests pass on Jenkins.

These tests are run on an internal Jenkins and results are not available to the wider community.

No automated tests are required for this ticket.

Thanks for adding this issue @ilopmar. We will get this fixed soon.

[molivasdat]

I just found out this is a duplicate of #1689, we are fixing it under that one that is slated for 4.3.2.

[ilopmar]

@molivasdat Thanks for the update. Regarding my last comment:

I've tried to workaround this problem by creating the file src/main/resources/liquibase.properties with content liquibase.headless=true but it is not working. I've also tried setting the LIQUIBASE_HEADLESS environment variable but that doesn't work either. What am I missing here?

Is this suppose to work? Is there any way to set any of those liquibase configuration properties?

[molivasdat]

Try to set the liquibase.headless=false as a system property it will not prompt

[nvoxland]

I had mistyped to @molivasdat , the property needs to be liquibase.headless=true, not false.

We are in the process of improving how the global configurations like that can be managed, including adding support for environment variables and the liquibase.properties file from spring boot etc.

For now, it is best set with a java system property if you are able to do that.

[ilopmar]

Thanks! Using a system property works as a workaround :-)

As I think you will release 4.3.2 soon I'll wait and the upgrade the Micronaut integration once you release the new version.

Thanks again for your help!

Iván López, thank you for writing such excellent reproduction steps and providing an example project.

[wind57]

it could also be specified as --headless true, which is great when this is part of a bigger script
