Getting Started

• Read through the quickstart guide for development. It will include information on getting a local copy of the source, give pointers on issue tracking, and provide some warnings about common problems with development environments.

• For a more comprehensive guide to development and information about contributing to the project read through the NiFi Developer's Guide.

• Optional: Build supporting modules. This should only be needed if the current 'nifi' module is in the process of updating to a new version of either the 'nifi-parent' or 'nifi-nar-maven-plugin' artifacts.

  If in doubt, just skip to building the main nifi project. If the build fails, come back here and figure out which optional step you are missing; each entry below will give an example of the errors you'll receive if that step needs to be followed. The version numbers may change but the error text should still look very familiar.

  • Install the nifi-parent pom. Change directory to 'nifi-parent' and follow the directions found there in README.md.

  If you don't build the nifi-parent pom and the main nifi code relies on an unreleased version you'll see an erorr like the following:

    [ERROR]     Non-resolvable parent POM: Could not find artifact
        org.apache.nifi:nifi-parent:pom:1.0.0-SNAPSHOT in example.snapshots.repo
        (https://repository.example.com/content/repositories/snapshots) and
        'parent.relativePath' points at no local POM @ line 18, column 13 -> [Help 2]
  

  • Build the nifi-nar-maven-plugin. Change directory to 'nifi-nar-maven-plugin' and follow the directions found there in README.md.

  If you don't build the nifi-nar-maven-plugin and the main nifi code relies on an unreleased version you'll see an error like the following:

    [ERROR]     Unresolveable build extension: Plugin
        org.apache.nifi:nifi-nar-maven-plugin:1.0.1-SNAPSHOT or one of its
        dependencies could not be resolved: Could not find artifact
        org.apache.nifi:nifi-nar-maven-plugin:jar:1.0.1-SNAPSHOT -> [Help 2]
  

• Build nifi. Change directory to 'nifi' and follow the directions found there in README.md.

• Run NiFi. The directions found in the README.md file within the 'nifi' module will also include how to run an instance of NiFi. For help on how to build your first data flow, see the NiFi User Guide.
