Build is broken on Windows

[DavidPratten]

Hi Julian,

I did a clean install of Java SDK 1.7, Maven 3.8.3 and then cloned and built following: https://github.com/julianhyde/morel#download-and-build

I received these failed tests after build.

mavin morel install fail.log

Next steps?

I'm surprised you can build at all using JDK 1.7. With JDK 1.7 I get

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:3.0.0:check (validate) on project morel: Execution validate of goal org.apache.maven.plugins:maven-checkstyle-plugin:3.0.0:check failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-checkstyle-plugin:3.0.0:check: java.lang.UnsupportedClassVersionError: com/puppycrawl/tools/checkstyle/api/AuditListener : Unsupported major.minor version 52.0

However, ./mvnw clean install works for me if I use JDK 8 and either maven-3.6.3 (the version embedded in mvnw) or maven-3.8.3.

Are you using the latest master, ab10217?

The errors in ShellTest are not that worrying. I think there is a race condition in jline where the echoed input and the output sometimes switch orders. It doesn't happen interactively, only during testing.

Are you running on Windows? The other errors might be due to differences in line endings. I develop on macOS and Linux.

Gave up on Windows.

From blank Ubuntu WSL2 shell under Windows 10:

$ sudo apt install default-jdk 

Then as per https://github.com/julianhyde/morel#download-and-build

Thanks for the pointers.

David

I've re-opened. Even though I don't have a fix, people should know: Build is broken on Windows. Workaround is to not use Windows. Contributions welcome!
