love to help!\n\n* If you are new to Spring Data JDBC read the following two articles https://spring.io/blog/2018/09/17/introducing-spring-data-jdbc[\"Introducing Spring Data JDBC\"] and https://spring.io/blog/2018/09/24/spring-data-jdbc-references-and-aggregates[\"Spring Data JDBC, References, and Aggregates\"].\n* Check the\nhttps://docs.spring.io/spring-data/relational/reference/[reference documentation], and https://docs.spring.io/spring-data/jdbc/docs/current/api/[Javadocs].\n* Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation.\nIf you are just starting out with Spring, try one of the https://spring.io/guides[guides].\n* If you are upgrading, check out the https://github.com/spring-projects/spring-data-relational/releases[changelog] for \"`new and noteworthy`\" features.\n* Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data[`spring-data`].\n\n== Reporting Issues\n\nSpring Data uses GitHub as issue tracking system to record bugs and feature requests.If you want to raise an issue, please follow the recommendations below:\n\n* Before you log a bug, please search the Spring Data JDBCs https://github.com/spring-projects/spring-data-relational/issues[issue tracker] to see if someone has already reported the problem.\n* If the issue doesn’t already exist, https://github.com/spring-projects/spring-data-relational/issues/new[create a new issue].\n* Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using and JVM version.\nPlease include full stack traces when applicable.\n* If you need to paste code, or include a stack trace use triple backticks before and after your text.\n* If possible try to create a test-case or project that replicates the issue.\nAttach a link to your code or a compressed file containing your code.\nUse an in-memory database when possible.\nIf you need a different database include the setup using https://github.com/testcontainers[Testcontainers] in your test.\n\n== Building from Source\n\nYou don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper].\nYou also need JDK 17.\n\n[source,bash]\n----\n $ ./mvnw clean install\n----\n\nIf you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.8.0 or above].\n\n_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change._\n\n=== Running Integration Tests\n\n[source,bash]\n----\n $ ./mvnw clean install\n----\n\nRuns integration test against a single in memory database.\n\nTo run integration tests against all supported databases specify the Maven Profile `all-dbs`.\n\n[source,bash]\n----\n./mvnw clean install -Pall-dbs\n----\n\nThis requires an appropriate `container-license-acceptance.txt` to be on the classpath, signaling that you accept the license of the databases used.\n\nIf you don't want to accept these licences you may add the Maven Profile `ignore-missing-license`.\nThis will ignore the tests that require an explicit license acceptance.\n\n[source,bash]\n----\n./mvnw clean install -Pall-dbs,ignore-missing-license\n----\n\nIf you want to run an integration tests against a different database you can do so by activating an appropriate Spring Profile.\nAvailable are the following Spring Profiles:\n\n`db2`, `h2`, `hsql` (default), `mariadb`, `mssql`, `mysql`, `oracle`, `postgres`\n\n=== Building reference documentation\n\nBuilding the documentation builds also the project without running tests.\n\n[source,bash]\n----\n $ ./mvnw clean install -Pantora\n----\n\nThe generated documentation is available from `spring-data-jdbc-distribution/target/antora/site/index.html`.\n\n== Modules\n\nThere are a number of modules in this project, here is a quick overview:\n\n* Spring Data Relational: Common infrastructure abstracting general aspects of relational database access.\n* link:spring-data-jdbc[Spring Data JDBC]: Repository support for JDBC-based datasources.\n* link:spring-data-r2dbc[Spring Data R2DBC]: Repository support for R2DBC-based datasources.\n\n== Examples\n\n* https://github.com/spring-projects/spring-data-examples/[Spring Data Examples] contains example projects that explain specific features in more detail.\n\n== License\n\nSpring Data Relational is Open Source software released under the https://www.apache.org/licenses/LICENSE-2.0.html[Apache 2.0
