Java mods and Bedrock add-ons are different
A Java mod built around a Java mod loader is not normally installed into MCPE by moving the same file into a Bedrock folder.
Package formats differ
A matching project name does not make files cross-compatible between Java and Bedrock editions.
Avoid unofficial repackaging claims
Be cautious with downloads that promise a direct port without clear authorship, file information or version support.
Use platform-native instructions
If you want the Java mod experience, create a compatible Java profile and follow loader-specific setup guidance.
Practical takeaway
Keep the setup reversible. A separate profile, a world backup and a written record of versions make updates and troubleshooting far easier than reconstructing a working environment after several changes.
