Reading file from resource - path must exist: /app/app.jar!/BOOT-INF/classes!/features/

Question

I need the classpath of a file. I found this way to get the path using classpath

String filePath = com.google.common.io.Resources.getResource(feature).getFile();

I deployed my app on my server. Executing my code with cucumber I got this error.

path must exist: /app/app.jar!/BOOT-INF/classes!/features/attachment/heal.feature

I checked the app.jar inside target folder and I am not enable to extract and see the content

I am using pring boot 2 and this is the pom

looks like jar is corrupt

Answer 1

I need the classpath of a file. I found this way to get the path using classpath

String filePath = >com.google.common.io.Resources.getResource(feature).getFile();

I deployed my app on my server. Executing my code with cucumber I got this error.

path must exist: /app/app.jar!/BOOT-INF/classes!/features/attachment/heal.feature

The file path is not the same as the classpath. If you look at the spring executable jar format you'll see a layout that is different from a regular jar file:

example.jar
 |
 +-META-INF
 |  +-MANIFEST.MF
 +-org
 |  +-springframework
 |     +-boot
 |        +-loader
 |           +-<spring boot loader classes>
 +-BOOT-INF
    +-classes
    |  +-mycompany
    |     +-project
    |        +-YourClasses.class
    +-lib
       +-dependency1.jar
       +-dependency2.jar

The contents of BOOT-INF/classes and BOOT-INF/lib are on the classpath. So you can use classpath:features/attachment/heal.feature as your feature path.

Do note that Cucumber only has limited support for scanning spring jar files.
