I am trying to make a web-service using spring-boot with gretty. It works well when calling appStart in gradle, but it would show error when calling appStartWar.
This is the error:

It seems that it could not find the main class in war file, but the com.example.server.Application really exists in war with path WEB-INF/classes/com/example/server
build.gradle
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'spring-boot'
apply plugin: 'org.akhikhl.gretty'
buildscript {
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'org.akhikhl.gretty:gretty:1.1.8'
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.2.2.RELEASE'
}
}
dependencies{
compile 'org.springframework.boot:spring-boot-starter-web:1.2.2.RELEASE'
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
}
gretty {
springBoot = true
springBootVersion = '1.2.2.RELEASE'
httpsEnabled = true
}
Application.java
@RestController
@SpringBootApplication
class Application extends SpringBootServletInitializer {
public static void main( String[] args ) {
SpringApplication.run( Application.class, args );
}
@Override
protected SpringApplicationBuilder configure( SpringApplicationBuilder builder ) {
return builder.sources( Application.class );
}
@RequestMapping( value = "test", method = RequestMethod.GET )
public String test() {
return "success";
}
}
Any help appreciated :)
Here's my project in Gitlab link
I've tried to deploy war to tomcat-7 directly, but it failed as well. So I think this is not a gretty problem.
