Hey @hongmiao-wu, thanks for the report.

In these situations, the best solution is to try running the PostgreSQL database manually using the following commands:

cd /var/folders/dc/rmhssxvx42z7vcp49_md0_d80000gp/T/embedded-pg/PG-ba8cd9274b4f86c8aaab345231d9cd72/bin
mkdir ./data && ./pg_ctl -D ./data start

The output should provide the Postgres database log, where the cause of the problem should be mentioned. If the database starts without issues, the problem is likely related to the permissions of the Java process that is trying to run the embedded Postgres.

You can check a similar issue here: #115

Unfortunately, it does not work.

First, it shows directory "data" is not a database cluster directory, then I use initdb -D ./data before starting.

Then PostgreSQL server starts successfully waiting for server to start....2025-02-22 10:33:45.465 CET [29417] LOG: starting PostgreSQL 14.15 (Homebrew) on aarch64-apple-darwin22.6.0, compiled by Apple clang version 15.0.0 (clang-1500.1.0.2.5), 64-bit

But the app(JabRef) I wanted to run still throws the same error I mentioned above
`

PostgreSQL 14.15 (Homebrew) - This doesn't look like binary files from this project. You need to use the ./ prefix when calling commands to ensure you're running files in the current directory, not global ones on the PATH. Currently, you're probably running the Homebrew version of PostgreSQL.

LInk to code:

Hey everyone,
I'm getting a similar (if not the same?) error when trying to build. Restarting my machine didn't help either unfortunately.

Console Output:

i tried to follow the JabRef-Setup very closely but encountered this at this step:
https://devdocs.jabref.org/getting-into-the-code/guidelines-for-setting-up-a-local-workspace/intellij-12-build.html

possibly noteworthy: I installed git and java on a seperate drive to my OS. I updated the path to git manually in the settings so i could pull from the forked repo.

edit: I stopped the build process and got this as console output:
Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

found something: i ran the command by hand and got this popup

grabbed the latest visual c++ redist and installed it. solved the issue!

@iloveskittles82 Thank you for the info. I hope the original issue has also been addressed, so I'm closing this issue.
