Running examples in Intellij/Idea requires src/test/generated-assertions to be marked as a test source folder

[HappyRay]

I tried the following version:

commit 518ca73 (HEAD -> master, origin/master, origin/HEAD)
Author: Joel Costigliola [email protected]
Date: Sun May 21 15:50:31 2017 +1200

use assertj-core 3.8.0

in Intellij 2017.2.

Running
org.assertj.examples.ArrayAssertionsExamples
for example in the IDE
caused compilation errors.

After I marked src/test/generated-assertions as a test source folder, it started to work.

The README says:
"In your IDE, add src/test/generated-assertions to the project java sources if you IDE shows errors/missing classes. This folder is where custom assertions classes are generated, it shows what you have with the maven assertions generator plugin."

Is this instruction correct?

[joel-costigliola]

have you run mvn clean install to generate the sources before importing the project ?

[HappyRay]

Yes.

Sample compilation errors:

[joel-costigliola]

is that the result of mvn clean install or the project in your IDE ?

[HappyRay]

In IDE.

mvn clean install worked fine.

[joel-costigliola]

Then you haven't imported the project correctly in your IDE, from what I see assertj-core dependency is missing is your IDE project.

[HappyRay]

I imported the project by loading the pom.xml file as a project into the intellij IDE. Is there a better/correct way to import the project?

[joel-costigliola]

I have reproduced the problem, it seems that Intellij Idea is not importing the project correctly, it sets test/generated-assertions as a source folder (in blue) instead of a test (in green), if you change it to a test folder in the module settings all will compile fine.

[HappyRay]

Thanks. That's what I discovered too. See the issue description.
I did a google search and couldn't find an answer.
I hope by filing an issue here at least others who run into the same problem can hopefully find a solution/workaround.

[joel-costigliola]

I will update the documentation but it is an Intellij Idea problem.

Thanks for reporting this.

[HappyRay]

I understand.

Thanks!

[joel-costigliola]

I have just updated the README.md, can you tell me if this is clear enough ?

[HappyRay]

Yes, it is clear.

Thanks!

I am having almost the same problem with Eclipse. I am getting
package org.assertj.core.api does not exist
even though I am specifying in my pom, version 3.6.2 while using JDK 1.8.
How to overcome it ?
mvn clean install is failing.

Try a maven refresh project from eclipse.

[joel-costigliola]

@PrasadNutalapati can you show the pom.xml ?
Please check is Basil's answer in https://stackoverflow.com/questions/54393445/cannot-resolve-symbol-assertions-error-message-when-trying-to-use-assertj addresses your issue.

[PrasadNutalapati]

I overcome this problem by removing the test for the dependency assertJ. This made the code compile and run, but the tests are not running, because the classes which invoke the assertions are in src/main/java folder.
Is there a scope which is super set of 'test' ?

[joel-costigliola]

compile is I believe but you can check that on the maven doc https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

Have you +1 Basil's answer ?
