Multiline values Failed

[Kingg22]

Context:

• Spring boot 3.3.3
• Java JDK 21
• Maven 3.9.5
• Spring dotenv 4.0.0

What happened?
Using a .env file I put my rsa key in the form JWT_PRIVATE="-----BEGIN PRIVATE KEY-----
......
-----END PRIVATE KEY-----"
and the error occurs:

14:29:57.810 [main] ERROR org.springframework.boot.SpringApplication -- Application run failed
io.github.cdimascio.dotenv.DotenvException: Malformed entry

I ran with ' ', with \n and the only solution I found was to use PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\nKh9NV...\n-----END RSA PRIVATE KEY-----\n" as the dotenv faq says.

I report it here since the error indicates the exception from here and not spring dotenv.

With \n and ' '

In this you can see that when using JWT_PRIVATE as a long string it does pass and the error is the following JWT_PUBLIC

Attentive to your response or solution. Thanks for all.

After reviewing the tests, it seems that the only way to define a multiline value is using this format: MULTI_LINE=hello\nworld (.env).

However, there appears to be an issue in the unit test. The test expects a multiline string with escaped newlines (\\n), but it should handle actual newlines (\n) instead (BasicTests.java).

A workaround could involve defining the multiline values in the format MULTI_LINE=hello\nworld and then replacing the escaped newlines with actual newlines using .replace("\\n", "\n") in java code. In any case, it would be best to wait for a fix for this issue.
