Notice: this plugin was originally developed at [revolut-engineering/jooq-plugin](https://github.com/revolut-engineering/jooq-plugin), but since
I can't publish it under the same group, I had to change the group from `com.revolut` to `dev.monosoul`.
---
This repository contains Gradle plugin for generating jOOQ classes in dockerized databases.
Plugin registers task `generateJooqClasses` that does following steps:
* pulls docker image
* starts database container
* runs migrations using Flyway
* generates jOOQ classes
---
The plugin uses [testcontainers library](https://www.testcontainers.org) to spin up the DB container.
To avoid conflicts with other plugins using docker java library or testcontainers, the plugin shades testcontainers
library and it's dependencies into `dev.monosoul.jooq.shadow` package.
Due to that in case you'd like to
[customize docker client strategy](https://www.testcontainers.org/features/configuration/#customizing-docker-host-detection),
the class names will have to be prefixed with `dev.monosoul.jooq.shadow`, while the property name will be
`dev.monosoul.jooq.docker.client.strategy` instead of `docker.client.strategy`. E.g.:
```properties
dev.monosoul.jooq.docker.client.strategy=dev.monosoul.jooq.shadow.org.testcontainers.dockerclient.EnvironmentAndSystemPropertyClientProviderStrategy
```
Also, instead of `TESTCONTAINERS_DOCKER_CLIENT_STRATEGY` environment variable, you should use
`DEV_MONOSOUL_JOOQ_TESTCONTAINERS_DOCKER_CLIENT_STRATEGY`.
# Examples
Detailed examples are available in the [examples directory](examples) of this repository.
By default plugin is configured to work with PostgreSQL, so the following minimal config is enough:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
dependencies {
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
It will look for migration files in `src/main/resources/db/migration` and will output generated classes
to `build/generated-jooq` in package `org.jooq.generated`. All of that details can be configured on the task itself
as shown in examples below.
Configuring schema names and other parameters of the task:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
schemas.set(listOf("public", "other_schema"))
basePackageName.set("org.jooq.generated")
migrationLocations.setFromFilesystem("src/main/resources/db/migration")
outputDirectory.set(project.layout.buildDirectory.dir("generated-jooq"))
flywayProperties.put("flyway.placeholderReplacement", "false")
includeFlywayTable.set(true)
outputSchemaToDefault.add("public")
schemaToPackageMapping.put("public", "fancy_name")
usingJavaConfig {
/* "this" here is the org.jooq.meta.jaxb.Generator configure it as you please */
}
}
}
dependencies {
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
To configure the plugin to use another version or edition of Flyway the following config can be used:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
dependencies {
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
jooqCodegen("org.postgresql:postgresql:42.3.6")
jooqCodegen("org.flywaydb.enterprise:flyway-core:${RecommendedVersions.FLYWAY_VERSION}")
jooqCodegen("org.flywaydb:flyway-database-postgresql:${RecommendedVersions.FLYWAY_VERSION}")
}
```
To configure the plugin to use another version or edition of jOOQ the following config can be used:
```kotlin
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
val jooqVersion = "3.15.10"
dependencies {
implementation("org.jooq:jooq:$jooqVersion")
jooqCodegen("org.postgresql:postgresql:42.3.6")
jooqCodegen("org.jooq:jooq-codegen:$jooqVersion")
}
```
To configure the plugin to work with another DB like MySQL the following config can be applied:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
jooq {
withContainer {
image {
name = "mysql:8.0.29"
envVars = mapOf(
"MYSQL_ROOT_PASSWORD" to "mysql",
"MYSQL_DATABASE" to "mysql"
)
}
db {
username = "root"
password = "mysql"
name = "mysql"
port = 3306
jdbc {
schema = "jdbc:mysql"
driverClassName = "com.mysql.cj.jdbc.Driver"
}
}
}
}
dependencies {
implementation("org.jooq:jooq:3.16.5")
jooqCodegen("mysql:mysql-connector-java:8.0.29")
jooqCodegen("org.flywaydb:flyway-mysql:${RecommendedVersions.FLYWAY_VERSION}")
}
```
To register custom types:
```kotlin
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
usingJavaConfig {
database.withForcedTypes(
ForcedType()
.withUserType("com.google.gson.JsonElement")
.withBinding("com.example.PostgresJSONGsonBinding")
.withTypes("JSONB")
)
}
}
}
dependencies {
implementation("org.jooq:jooq:3.16.5")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
To use XML-based configuration:
```kotlin
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
usingXmlConfig()
}
}
dependencies {
implementation("org.jooq:jooq:3.16.5")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
by default the path to the XML config is `src/main/resources/db/jooq.xml`, where it's content looks as following:
```xml
public
.*
JSONB
com.google.gson.JsonElement
com.example.PostgresJSONGsonBinding
```
To customize the XML config path:
```kotlin
tasks {
generateJooqClasses {
usingXmlConfig(project.layout.projectDirectory.file("src/main/resources/db/other-jooq-config.xml"))
}
}
```
To customize the loaded XML config:
```kotlin
tasks {
generateJooqClasses {
usingXmlConfig {
database.withExcludes("BAR")
}
}
}
```
To exclude flyway schema history table from generated classes:
```kotlin
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
schemas.set(listOf("other"))
usingJavaConfig {
database.withExcludes("flyway_schema_history")
}
}
}
dependencies {
implementation("org.jooq:jooq:3.16.5")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
### Remote docker setup
If you want to use the plugin with remote docker instance, refer to the
[testcontainers documentation](https://www.testcontainers.org/features/configuration/#customizing-docker-host-detection)
.
### Remote database setup
The plugin supports remote database setup, where an external DB can be used to generate jOOQ classes instead of
spinning up a container with the DB. This setup can also be convenient when a container with the DB is created
externally (for example with Docker compose).
To use the plugin with a remote DB:
```kotlin
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
jooq {
withoutContainer {
db {
username = "postgres"
password = "postgres"
name = "postgres"
host = "remotehost"
port = 5432
}
}
}
dependencies {
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
### Multi-database setup
The plugin supports multi-database setup, where jOOQ classes could be generated out of different RDBMS.
This could be achieved by registering a separate class generation task for every RDBMS.
Here's an example how to generate jOOQ classes for PostgreSQL and MySQL in a single project:
```kotlin
import dev.monosoul.jooq.GenerateJooqClassesTask
import dev.monosoul.jooq.RecommendedVersions
plugins {
kotlin("jvm") version "1.6.21"
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
basePackageName.set("org.jooq.generated.postgres")
migrationLocations.setFromFilesystem("src/main/resources/postgres/migration")
outputDirectory.set(project.layout.buildDirectory.dir("postgres"))
}
register("generateJooqClassesForMySql") {
basePackageName.set("org.jooq.generated.mysql")
migrationLocations.setFromFilesystem("src/main/resources/mysql/migration")
outputDirectory.set(project.layout.buildDirectory.dir("mysql"))
withContainer {
image {
name = "mysql:8.0.29"
envVars = mapOf(
"MYSQL_ROOT_PASSWORD" to "mysql",
"MYSQL_DATABASE" to "mysql"
)
}
db {
username = "root"
password = "mysql"
name = "mysql"
port = 3306
jdbc {
schema = "jdbc:mysql"
driverClassName = "com.mysql.cj.jdbc.Driver"
}
}
}
}
}
dependencies {
implementation(kotlin("stdlib"))
jooqCodegen("org.postgresql:postgresql:42.3.6")
jooqCodegen("mysql:mysql-connector-java:8.0.29")
jooqCodegen("org.flywaydb:flyway-mysql:${RecommendedVersions.FLYWAY_VERSION}")
jooqCodegen("org.flywaydb:flyway-database-postgresql:${RecommendedVersions.FLYWAY_VERSION}")
implementation("org.jooq:jooq:3.16.6")
}
```
where:
- For PostgreSQL:
- migrations are located in `src/main/resources/postgres/migration`
- generated classes are located in `build/postgres` under `org.jooq.generated.postgres` package
- For MySQL:
- migrations are located in `src/main/resources/mysql/migration`
- generated classes are located in `build/mysql` under `org.jooq.generated.mysql` package
Basically, the plugin has 2 sets of configurations: **global** (or project-wide) configuration declared within `jooq {}`
block and **local** (or task-specific) configuration declared for each task separately.
Local (or task-specific) configuration initial values are inherited from the global (or project-wide) configuration.
So if you modify the global configuration first, and then modify the local configuration, the local configuration's
initial values will be equal to the global configuration's values.
Modifying the local configuration *will not affect* the global configuration.
### Configuration with properties
The plugin supports configuration with properties.
Here's an example of how to use `gradle.properties` file to configure the plugin to generate jOOQ classes for MySQL:
`gradle.properties`:
```properties
dev.monosoul.jooq.withContainer.db.username=root
dev.monosoul.jooq.withContainer.db.password=mysql
dev.monosoul.jooq.withContainer.db.name=mysql
dev.monosoul.jooq.withContainer.db.port=3306
dev.monosoul.jooq.withContainer.db.jdbc.schema=jdbc:mysql
dev.monosoul.jooq.withContainer.db.jdbc.driverClassName=com.mysql.cj.jdbc.Driver
dev.monosoul.jooq.withContainer.image.name=mysql:8.0.29
dev.monosoul.jooq.withContainer.image.envVars.MYSQL_ROOT_PASSWORD=mysql
dev.monosoul.jooq.withContainer.image.envVars.MYSQL_DATABASE=mysql
```
`build.gradle.kts`:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
kotlin("jvm") version "1.6.21"
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
dependencies {
jooqCodegen("mysql:mysql-connector-java:8.0.29")
jooqCodegen("org.flywaydb:flyway-mysql:${RecommendedVersions.FLYWAY_VERSION}")
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
}
```
And here's an example how to customize the plugin configuration from command line:
```shell
./gradlew build -Pdev.monosoul.jooq.withContainer.db.username=root -Pdev.monosoul.jooq.withContainer.db.password=password
```
#### ❗ NOTE: `withoutContainer` properties have higher priority than `withContainer` properties.
#### ❗ NOTE: properties only affect global (or project-wide) configuration.
### Java-based migrations
The plugin
supports [Java-based Flyway migrations](https://documentation.red-gate.com/fd/tutorial-java-based-migrations-184127624.html).
If you have Java-based migrations as a part of your project in a Gradle submodule, you can use the following
configuration:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
tasks {
generateJooqClasses {
migrationLocations.setFromClasspath(
project(":migrations").sourceSets.main.map { it.output },
"package/with/migrations"
)
}
}
dependencies {
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
If you want to run migrations provided in a JAR file by some third party:
```kotlin
import dev.monosoul.jooq.RecommendedVersions
plugins {
id("dev.monosoul.jooq-docker")
}
repositories {
mavenCentral()
}
val migrationClasspath by configurations.creating
tasks {
generateJooqClasses {
migrationLocations.setFromClasspath(
migrationClasspath,
"package/with/migrations"
)
}
}
dependencies {
implementation("org.jooq:jooq:${RecommendedVersions.JOOQ_VERSION}")
migrationClasspath("third.party:library:version")
jooqCodegen("org.postgresql:postgresql:42.3.6")
}
```
