IntelliJ Artifact has invalid extension

Question

I have strange a problem with deploying an artifact on jboss. After generating the default spring-mvc project in IntelliJ, I tried to run it, but IntelliJ showed in "Run/Debug Configuration" a message that my "Artifact XYZ:war exploded has invalid extension".

I found advice on stackoverflow "change extension" but I have correct .war extension.

What is wrong?

Answer 1

Simply add .war to your output directory name.

Unfortunately changing the pom.xml with Maven will probably result into a modification of the output directory, and you will have to do it again.

Answer 2

There is a bug report that's over two years old. Still hasn't been resolved. Here is another bug report, also two years old, that's marked as a duplicate.

Answer 3

This is the bug in IntelliJ. It does not support upper case on Artifact.

Answer 4

1. Open module settings (F4 on your project)
2. Go to artifacts

3. make sure that Output directory points to folder with suffix ".war"

   XXsomewar_exploded.war

If not, just delete all artifacts with red minus sign, and click then plus sign and select war exploaded. Then also select Build on make checkbox

Go also to your project on disk, and check folder out, if it containes exploaded war folder and if stuff is inside.
