Wrong classpath when Tomcat is launched in Idea

[Saumya]

There's a problem in the launch. Tomcat ♪ Idea♪

If you start a test class, it works. The point is, it's not the way to the project file, it's "replaced" by Tomcat'u♪

The path shall be:

C:\Users\AntonioPrime\IdeaProjects\ProjectName\src\main\resources\ingredients.txt

Code:

Files.lines(Paths.get("src/main/resources/ingredients.txt").toAbsolutePath()).filter(e -> !(e.equals(""))).forEach(e -> {
                Ingredient ingredient = constructIngredient(e);
                ingredients.put(ingredient.getName(), ingredient);
            });

Erroneous error for unclear reasons by other means:

java.nio.file.NoSuchFileException: C:\apache-tomcat-8.5.4\bin\src\main\resources\ingredients.txt

The point is, you have a relative path, so when you start your IDE code, it's one, and when it's done in the context of Tomkat, the other.
I understand this file is a resource in your project. To get a resource, use something like that. this.getClass().getResource("/ingredients.txt") or this.getClass().getResourceAsStream("/ingredients.txt")
P.S. Your question has nothing to do with classpath Tomcat :
