The question is simple, but I spent the last 2 days trying to deploy my app. And so far it doesn't.
I have a single CSS file for my style, and when I execute the jar, CSS is not found (404) or the jar won't package.
As stated here: Spring Boot Executable jar structure "Do not use the src/main/webapp folder if your application will be packaged as a jar" and "You should place your static resources in src/main/resources instead."
so put the CSS here: src/main/resources/styles.css
In Vaadin documentation (which is very pour on how to package...) I import the CSS like this:
@StyleSheet("styles.css")
Source : https://vaadin.com/docs/v11/flow/importing-dependencies/tutorial-include-css.html
Then I package my project:
mvn clean package -Pproduction
I get this error:
[ERROR] Failed to execute goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production (default) on project importparcoursup: Execution default of goal com.vaadin:vaadin-maven-plugin:11.0.0:package-for-production failed: An import that ends with 'styles.css' cannot be resolved: the corresponding file 'C:\Workspace\lasteclipeandjava10\parcoursup\target\frontend\styles.css' was not found.
[ERROR] Double check the corresponding import and verify the following:
[ERROR] * the import string is correct
[ERROR] * the file imported is either present in 'frontend://' directory of the project or in one of the project WebJar dependencies or in one of the regular jar dependencies
[ERROR] * if the file is present in one of the regular jar dependencies, it should be located inMETA-INF/resources/frontenddirectory in the jar
Can someone provide a simple example of a 'springboot + Vaadin10' app packaged as a jar with static resources inside ?
I tried so many configurations (put the CSS in META-INF, include webapp resources in the maven build process...) but after 2 days, I still can't deploy my app on the server!
css has to be here:
src/main/resources/META-INF/resources/frontend/styles.css
then declared as:
@StyleSheet("frontend://styles.css")
