Use Spring's `propdeps` plugin to introduce optional/provided scopes for gradle dependencies. Mark libraries such as slf4j-log4j12 as optional. These libraries are required to run a local ethereumj node, but they are not required in order to compile against ethereumj in a downstream appliaction. These libraries easily can cause conflicts, for example if another slf4j-* library (such as slf4j-logback) is on the classpath.
Welcome to ethereumj
About
ethereumj is a pure-Java implementation of the Ethereum protocol. For high-level information about Ethereum and its goals, visit ethereum.org. The ethereum white paper provides a complete conceptual overview, and the yellow paper provides a formal definition of the protocol.
This repository consists of:
- ethereum-core: a library suitable for inclusion in any JVM-based project.
- ethereum-studio: a simple GUI for exploring Ethereum functionality and usage of the ethereumj API.
To see ethereum-studio in action, watch this video.
Todo
The Ethereum protocol is under heavy development, thus so is this implementation. See the todo list, GitHub Issues and milestone schedule. Issues are prioritized using waffle.

Building from source
- Clone this repository and run
./gradlew build(or at least./gradlew antlr4to generate sources). - Import all sources into IntelliJ IDEA (14+) with
File->Import projectand point to the top-levelbuild.gradlefile. - Make sure to set your language level in
File->Project Structure...to JDK 8. - Run
Build->Make Project. When complete, there should be no errors.
