The sections below describe how to import the Flink project into an IDE for the development of Flink itself. For writing Flink programs, please refer to the Java API and the Scala API quickstart guides.
NOTE: Whenever something is not working in your IDE, try with the Maven
command line first (
mvn clean package -DskipTests) as it might be your IDE
that has a bug or is not properly set up.
To get started, please first checkout the Flink sources from one of our repositories, e.g.
git clone https://github.com/apache/flink.git
A brief guide on how to set up IntelliJ IDEA IDE for development of the Flink core. As Eclipse is known to have issues with mixed Scala and Java projects, more and more contributers are migrating to IntelliJ IDEA.
The following documentation describes the steps to setup IntelliJ IDEA 2016.2.5 (https://www.jetbrains.com/idea/download/) with the Flink sources.
The IntelliJ installation setup offers to install the Scala plugin. If it is not installed, follow these instructions before importing Flink to enable support for Scala projects and files:
mvn clean package -DskipTestsalso creates the necessary files for the IDE to work with but without installing libraries.
NOTE: From our experience, this setup does not work with Flink due to deficiencies of the old Eclipse version bundled with Scala IDE 3.0.3 or due to version incompatibilities with the bundled Scala version in Scala IDE 4.4.1.
We recommend to use IntelliJ instead (see above)
