Settting up environment

Table of Contents

The project is developed using Intelliji Idea. Community Edition should work fine. All further steps assume you have it already installed.

Preliminary steps

  • Make sure you have Java 8 installed (the JDK version is as an example, Oracle JDK will do either):
> java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.252-b09, mixed mode)
  • Clone repository
git clone
  • Make your first build and wait test to pass. No special requirements here.
./gradlew build

Install plugins

A few extra plugins you need to make sure you have installed.

Import project

To import the project just open via File > Open in IDE the build.gradle.kts file in the root directory of the project, select Open as project. Select to use gradle wrapper.

Setting up build configurations

A few basic configurations are handy to create. Especially for running tests. As by the time of writing this there was no way found to run all tests at once, as well as using Spek plugin. So you need to cre JUnit runner and repeat steps for all projects (lib, exe, cli, http).

  • Create configuration, then select JUnit.
  • Name configuration, for example LIB tests.
  • Select Test kind: All in package.
  • Select Search for tests: In single module.
  • Select Use classpath or module: io.wavebeans.lib.test (or corresponding to the project).
  • Add additional VM option -DSPEK_TIMEOUT=0 as some tests are taking more than default 10 seconds timeout and failing weirdly.

While working on Protobuf stuff

IDE doesn’t currently build automatically proto-files, but all source folders are configured correctly. Every time you change them (or cleaned the project) regenerate them by running gradle command:

./gradlew clean generateProto

Dropbox integration testing

When running all tests or testing DropBox related stuff, you may need to specify dropbox integration parameters. They are specified via environment variables DBX_TEST_CLIENT_ID and DBX_TEST_ACCESS_TOKEN. On GitHub they are stored in project secrets and are being provided during build time, though on your local environment you may create your own.

First of all follow the docs to fetch required values. And then:

  • To run via gradle, use export if you’re on zsh-like shell or store commands directly into you .zshrc:
      export DBX_TEST_CLIENT_ID=test-client-id
      export DBX_TEST_ACCESS_TOKEN=access-token
  • To conveniently run in Intelliji IDEA and a default parameter into and Spek runners:
    • Run/Debug configurations > Templates > Spek 2 - JVM
    • Add both values under environment variables.
