Building the project

This project is built with Maven. Source code is available on GitHub. Thanks to JetBrains for the IntelliJ IDEA License!

Jet Brains

Clone the project

Use git to clone the project locally:

git clone git@github.com:dadoonet/fscrawler.git
cd fscrawler

Build the artifact

To build the project, run:

mvn clean package

The final artifacts are available in distribution/esX/target directory where X is the elasticsearch major version target.

Tip

To build it faster (without tests), run:

mvn clean package -DskipTests

Integration tests

When running from the command line with mvn integration tests are ran against all supported versions. This is done by running a Docker instance of elasticsearch using the expected version.

Run tests from your IDE

To run integration tests from your IDE, you need to start tests in fscrawler-it-common module. But you need first to specify the Maven profile to use and rebuild the project.

  • es-6x for Elasticsearch 6.x
  • es-5x for Elasticsearch 5.x

Run tests with an external cluster

To run the test suite against an elasticsearch instance running locally, just run:

mvn verify -pl fr.pilato.elasticsearch.crawler:fscrawler-it-v6

Tip

If you want to run against a version 5, run:

mvn verify -pl fr.pilato.elasticsearch.crawler:fscrawler-it-v5

If elasticsearch is not running yet on http://localhost:9200, FSCrawler project will run a Docker instance before the tests start.

Hint

If you are using a secured instance, use tests.cluster.user, tests.cluster.pass and tests.cluster.url:

mvn verify -pl fr.pilato.elasticsearch.crawler:fscrawler-it-v6 \
    -Dtests.cluster.user=elastic \
    -Dtests.cluster.pass=changeme \
    -Dtests.cluster.url=https://127.0.0.1:9200 \

Hint

To run tests against another instance (ie. running on Elasticsearch service by Elastic, you can also use tests.cluster.url to set where elasticsearch is running:

mvn verify -pl fr.pilato.elasticsearch.crawler:fscrawler-it-v6 \
    -Dtests.cluster.user=elastic \
    -Dtests.cluster.pass=changeme \
    -Dtests.cluster.url=https://XYZ.es.io:9243

Or even easier, you can use the Cloud ID available on you Cloud Console:

mvn verify -pl fr.pilato.elasticsearch.crawler:fscrawler-it-v6 \
    -Dtests.cluster.user=elastic \
    -Dtests.cluster.pass=changeme \
    -Dtests.cluster.cloud_id=fscrawler:ZXVyb3BlLXdlc3QxLmdjcC5jbG91ZC5lcy5pbyQxZDFlYTk5Njg4Nzc0NWE2YTJiN2NiNzkzMTUzNDhhMyQyOTk1MDI3MzZmZGQ0OTI5OTE5M2UzNjdlOTk3ZmU3Nw==

Tests options

Some options are available from the command line when running the tests:

  • tests.leaveTemporary leaves temporary files after tests. false by default.
  • tests.parallelism how many JVM to launch in parallel for tests. Set to auto by default

    which means that it depends on the number of processors you have.

  • tests.output what should be displayed to the console while running tests. By default it is set to

    onError but can be set to always

  • tests.verbose false by default
  • tests.seed if you need to reproduce a specific failure using the exact same random seed
  • tests.timeoutSuite how long a single can run. It's set by default to 600000 which means 5 minutes.
  • tests.locale by default it's set to random but you can force the locale to use.
  • tests.timezone by default it's set to random but you can force the timezone to use.

For example:

mvn install -rf :fscrawler-it -Pes-6x -Dtests.output=always

Check for vulnerabilities (CVE)

The project is using OSS Sonatype service to check for known vulnerabilities. This is ran during the verify phase.

Sonatype provides this service but with a anonymous account, you might be limited by the number of tests you can run during a given period.

If you have an existing account, you can use it to bypass this limit for anonymous users by setting sonatype.username and sonatype.password:

mvn verify -DskipTests \
    -Dsonatype.username=youremail@domain.com \
    -Dsonatype.password=yourverysecuredpassword

If you want to skip the check, you can run with -Dossindex.fail=false:

mvn clean install -Dossindex.fail=false
