Description
Reports package declarations whose fully-qualified name contains any uppercase character.
Rationale
The Java language conventions reserve lowercase for package components. Mixed-case package names blur the boundary between a package reference and a type reference in qualified identifiers (com.Example.Thing makes Example look like a type). File systems are also case-insensitive on some platforms, which causes subtle classpath problems when a repository is cloned on Windows or macOS with default settings.
// Bad
package com.example.BadName;
// Good
package com.example.badname;
// or
package com.example.bad_name;
