[FIXED] Gradle not creating workable jar

Issue

The Github repo is https://github.com/jzheaux/terracotta-bank-spring and I want an executable jar file for this project so my steps are

1. ./gradlew bootJar

jar gets created successfully inside build/libs

2. cd build/libs

3. java -jar terracotta-bank-spring-0.0.1-SNAPSHOT.jar

Spring starts successfully

4. But when I click on localhost:8080

I get the below error when Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.

Mon Oct 12 18:43:47 SGT 2020 There was an unexpected error (type=Not Found, status=404). /index.jsp

Solution

This is a spring-mvc project with .jsp files. Jsp files are handled differently when run as a jar or inside a app server.

When you try to build the project with ./gradlew clean build a war file will be generated. You can run the war as a standalone server because it has embedded tomcat as a dependency. Just run

cd /build/libs
java -jar terracotta-bank-spring-0.0.1-SNAPSHOT.war

Then go to http://localhost:8080
