Hi @jdaugherty! I found the problem. Here is what I think we should do:
* The issue is that when a user sets GRAILS_REPO_URL to ~/.m2/repository the
shell doesn't expand the ~ because it's stored as an environment variable.
* When CreateAppCommand uses this value in the build.gradle template the ~
is taken literally. Gradle can't resolve it.
To fix this we can change CreateAppCommand.groovy to normalize the path
before putting it in the template. We can do this by replacing a leading ~ with
the user's home directory.
Here is how we can do it:
```groovy
String repoUrl = System.getenv("GRAILS_REPO_URL")
if (repoUrl != null && repoUrl.startsWith("~")) {
String homeDir = System.getProperty("user.home")
repoUrl = homeDir + repoUrl.substring(1)
}
```
This approach works on macOS, Linux, and Windows. It also doesn't rely on
behavior. We should also add a test case to make sure it works.
The test case will set GRAILS_REPO_URL to a path that starts with ~. Check
that the generated build.gradle has a full path.
I can make a request with this fix. Just let me know if this looks good or
if you want me to change something.
