Building StreamSets Data Collector

To build the Data Collector you will need the following software :

  • Git 1.9+
  • Oracle JDK 8
  • Docker 1.10+ (required only if running integration tests, older versions may work but are not tested.)
  • Maven 3.3.9+
  • Node 0.10.32+1 (macOS, brew install nodejs : Linux, or Packages from NodeSource)
  • npm (macOS, brew install nodejs : Linux, or Packages from NodeSource)
  • bower 1.8.2 (macOS, npm -g install bower : Linux, sudo npm -g install bower)
  • grunt-cli (macOS, npm -g install grunt-cli : Linux, sudo npm -g install grunt-cli)
  • md5sum (macOS, brew install md5sha1sum)

Prerequisite Tasks for Building Data Collector

If you're building master branch, then you need to install API and Plugin API modules to your maven cache first before compiling Data Collector. Released versions are published to public maven repositories and for them this step can be skipped.

  • You can do that by getting the latest code from Github

    git clone


    git clone

  • And install each of these to your local maven repository

    mvn clean install -DskipTests

You also need the artifacts for datacollector-edge installed into your local maven repository.

  • Ensure you have the prerequisites listed for building datacollector-edge

  • Get the latest version of datacollector-edge from Github

    git clone

  • Gradle is used in this project as a build tool, so in order to install it to your local maven repository execute:

    ./gradlew clean dist publishToMavenLocal

Finally, get the latest Data Collector code from Github

git clone

Development build

From within the Data Collector directory, execute:

mvn package -Pdist,ui -DskipTests

To start the Data Collector, execute:

dist/target/streamsets-datacollector-3.6.0-SNAPSHOT/streamsets-datacollector-3.6.0-SNAPSHOT/bin/streamsets dc

For Data Collector CLI, execute:

dist/target/streamsets-datacollector-3.6.0-SNAPSHOT/streamsets-datacollector-3.6.0-SNAPSHOT/bin/streamsets cli

To skip the RAT report during the build use the -DskipRat option.

Running integration tests

From within the Data Collector directory, execute:

mvn install -Pdist -DskipTests

Once the dependencies are installed, run the integration tests:

mvn failsafe:integration-test -DfailIfNoTests=false

In case you want to run a specific integration class (here the module basic-lib is executed with integration tests in 'HttpProcessorIT'):

mvn -pl basic-lib failsafe:integration-test -Dit.test="HttpProcessorIT" -DfailIfNoTests=false

Release build

From within the Data Collector directory, execute:

mvn package -Drelease -DskipTests

The release tarball will be created at:


Extract the tarball to your preferred location :

tar xf streamsets-datacollector-all-3.6.0-SNAPSHOT.tgz

To start the DataCollector, execute:

streamsets-datacollector-all-3.6.0-SNAPSHOT/bin/streamsets dc


Recent changes in Node might cause the build to fail with an error similar to:

Upgrade Node to the current version (at the time of writing, this was 10.7.0) and execute the following commands from the datacollector directory:

cd datacollector-ui
rm -rf node_modules
rm -rf package-lock.json
npm --force cache clean
npm install
