@mshima Can you help me with snapshots, on Windows I am not able to update them automatically because it add lot of slash like here:

generator-jhipster/test/__snapshots__/docker-compose.spec.js.snap

Line 91 in db3b9a9

context: 10-couchbase\\\\src\\\\main\\\\docker

Need to execute normalize-path at relativePath:

generator-jhipster/generators/docker-compose/index.js

Line 178 in 18013de

const relativePath = pathjs.relative(this.destinationRoot(), `${path}/src/main/docker`);

And here:

generator-jhipster/generators/docker-compose/index.js

Line 198 in 18013de

const cqlFilesRelativePath = pathjs.relative(this.destinationRoot(), `${path}/src/main/resources/config/cql`);

Probably it’s not only the snapshot that is affected.
