Error during deploy

Hi,

Strangely, I can’t deploy java apps at all, here is what I get:

 p/n/java-test nanobox deploy dry-run                                                                  (261ms)

I have tried to nanobox destroy. I've even tried to deploy an empty java app, where boxfile.yml was the only file in the project/directory and it contained these two lines only:

run.config:
  engine: java

Nanobox Version 2.3.0-171031T1616 (80207fe)
macos 10.13 High Sierra 😢

Hello,

I haven't deployed a java app yet, but I am testing with one, so I hope I can help.

What does your boxfile look like? Are you using maven as a build tool? Are you packaging your application into a final fat .jar? Are you using any kind of framework, like http://sparkjava.com/?

I generate a fat jar file with maven and have it configured so I can run a server with nanobox run "mvn exec:exec@run-app". This is my standard boxfile:

run.config:
  engine: java
  engine.config:
    runtime: oracle-jdk8
    maven_version: '3.3'

deploy.config:
  extra_steps:
    - mvn clean package

web.site:
  start: mvn exec:exec@run-app

data.queue:
  image: nanobox/redis:3.2
  config:
    databases: 4

It might be faster / get more awareness if you ask around in the #java channel on slack.

Hi @bnunamak,

thanks for the reply!

I'm not a java dev, I was just trying to deploy Graylog which is a bunch of jar files.

Turns out I was missing these strings:

  engine.config:
    runtime: oracle-jdk8
    gradle_version: '4.2'

So only

run.config:
  engine: java

is not enough, and engine.config is required. Not sure if it's bug or feature but it's undocumented.

Here is my boxfile for Graylog:

run.config:
  engine: java

  engine.config:
    compile: 'echo "skip compile"'
    runtime: oracle-jdk8
    gradle_version: '4.2'

  extra_path_dirs:
    - dist/bin

data.elasticsearch:
  image: nanobox/elasticsearch:5

data.mongodb:
  image: nanobox/mongodb:3.4

data.storage:
  image: nanobox/unfs

web.main:
  start: graylogctl run
  network_dirs:
    data.storage:
      - server
  ports:
    # Plaintext UDP
    - udp:5555:5555

    # nginx via Syslog UDP
    - udp:12401:12401
    - udp:12402:12402

deploy.config:
  transform:
    - bash ./setup.sh # generates config file from env vars

@minibikini Good catch. This is actually a use-case to allow users to disable the compile step so you can just use pre-built JARs that don't require compilation.
