java - Running Spring app built with gradle on Heroku -



java - Running Spring app built with gradle on Heroku -

i have problem spring application built gradle. app includes mongodb(mongohq heroku).

i managed how force on heroku, i've added code project:

@configuration public class mongohqconfiguration { public @bean mongodbfactory mongodbfactory() throws mongoexception, unknownhostexception { homecoming new simplemongodbfactory(new mongouri(system.getenv("mongohq_url"))); } public @bean mongotemplate mongotemplate() throws exception { homecoming new mongotemplate(mongodbfactory()); } }

after changing buildpacks 1 gradle, pushed on heroku free business relationship mongohq sandbox.

but after trying run app through web browser, i'm getting error:

an error occurred in application , page not served. please seek 1 time again in few moments.

if application owner, check logs details.

heroku logs gives me output:

i think problem in procfile, have no thought should add together there, here's current code:

default_process_types:

web: java $java_opts -jar build/libs/*.jar

here's build.gradle:

buildscript { repositories { maven { url "http://repo.spring.io/libs-release" } mavencentral() } dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:1.1.8.release") } } apply plugin: 'java' apply plugin: 'eclipse' apply plugin: 'idea' apply plugin: 'spring-boot' mainclassname = "com.shalastra.tvmaniac.tvmaniacconfiguration" jar { basename = 'tvmaniac' version = '0.1.0' } repositories { mavencentral() maven { url "http://repo.spring.io/libs-release" } maven { url "http://m2.neo4j.org" } } dependencies { compile("org.springframework.boot:spring-boot-starter-web") compile("org.springframework.boot:spring-boot-starter-actuator") testcompile("junit:junit") compile("org.springframework.data:spring-data-rest-webmvc") compile("org.springframework.data:spring-data-mongodb") compile("com.google.guava:guava:17.0") compile("org.apache.commons:commons-lang3:3.3.2") } task wrapper(type: wrapper) { gradleversion = '2.0' } task stage(dependson: ['clean', 'build', 'installapp'])

thanks in advance help.

after short give-and-take in comments seems (according this instructions) need add together next task build.gradle file:

task stage(type: copy, dependson: [clean, build]) { jar.archivepath project.rootdir rename { 'app.jar' } } stage.mustrunafter(clean) clean << { project.file('app.jar').delete() }

and content of procfile be:

web: java $java_opts -jar app.jar

now should work fine.

explanation:

task stage prepares jar file run. after it's finished output jar copied project.rootdir , renamed app.jar. guarantees have same name , can run command procfile. stage task depends on clean (which has additional action remove app.jar) , build (which builds app). it's of import set stage.mustrunafter(clean) because otherwise order in tasks run not determined (this happens - check locally). mean if dependson specified build may run, clean , stage - , nil created. hope it's clear.

java spring heroku deployment gradle
