Supported versions

Due to 3 major changes in dropwizard recently, 3 guicey versions supported:

Dropwizard	Guicey	Reason
2.1.x	5.x	Last java 8 compatible version (EOL January 31 2024)
3.x	6.x	Changed core dropwizard packages - old 3rd paty bundles would be incompatible
4.x	7.x	Jakarta namespace migration - 3rd party guice modules might be incompatible

All branches use the same project structure: core guicey merged with extension modules. It greatly simplifies releases and keeps actual examples in one branch.

Upcoming guicey changes would be ported in all 3 branches.

Setup

Maven:

<dependency>
  <groupId>ru.vyarus</groupId>
  <artifactId>dropwizard-guicey</artifactId>
  <version>7.2.2</version>
</dependency>

Gradle:

implementation 'ru.vyarus:dropwizard-guicey:7.2.2'

Dropwizard	Guicey
4.0	7.2.2
3.0	6.3.2
2.1	5.10.2
2.0	5.5.0
1.3	4.2.3
1.1, 1.2	4.1.0
1.0	4.0.1
0.9	3.3.0
0.8	3.1.0
0.7	1.1.0

GRADLE 6 users: You might face Could not resolve com.google.guava:guava:32.1.2-jre. problem. This caused by guava packaging issue (affected many people). Either upgrade to gradle 7-8 or apply workaround

BOM

Use BOM for guice, dropwizard and guicey modules dependency management. BOM usage is highly recommended as it allows you to correctly update dropwizard dependencies.

Gradle:

dependencies {
    implementation platform('ru.vyarus.guicey:guicey-bom:7.2.2')
    // uncomment to override dropwizard and its dependencies versions    
    //implementation platform('io.dropwizard:dropwizard-dependencies:4.0.14')

    // no need to specify versions
    implementation 'ru.vyarus:dropwizard-guicey'
    implementation 'ru.vyarus.guicey:guicey-eventbus'
   
    implementation 'io.dropwizard:dropwizard-auth'
    implementation 'com.google.inject:guice-assistedinject'   
    
    testImplementation 'io.dropwizard:dropwizard-testing'
}

Maven:

<dependencyManagement>  
    <dependencies>
        <dependency>
            <groupId>ru.vyarus.guicey</groupId>
            <artifactId>guicey-bom</artifactId>
            <version>7.2.2</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency> 
        <!-- uncomment to override dropwizard and its dependencies versions  
        <dependency>
            <groupId>io.dropwizard/groupId>
            <artifactId>dropwizard-dependencies</artifactId>
            <version>4.0.14</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency> -->                 
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>ru.vyarus</groupId>
        <artifactId>dropwizard-guicey</artifactId>
    </dependency>
</dependencies>

BOM includes:

BOM	Artifact
Guicey modules	ru.vyarus.guicey:guicey-[module]
Dropwizard BOM	io.dropwizard:dropwizard-bom
Guice BOM	com.google.inject:guice-bom
HK2 bridge	org.glassfish.hk2:guice-bridge
Spock-junit5	ru.vyarus:spock-junit5

Snapshots

Snapshots published into Maven Central

Add maven snapshots repository:

repositories {
        mavenLocal()
        mavenCentral()
        maven {
            name = 'Central Portal Snapshots'
            url = 'https://central.sonatype.com/repository/maven-snapshots/'
            mavenContent {
                snapshotsOnly()
                includeGroupAndSubgroups('ru.vyarus')
            }
        }
    }

Use snapshot version:

dependencies {
    implementation 'ru.vyarus:dropwizard-guicey:7.2.2-SNAPSHOT'
}

To avoid caching you may use:

configurations.all {
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

Maven:

<repositories>
    <repository>
        <name>Central Portal Snapshots</name>
        <id>central-portal-snapshots</id>
        <url>https://central.sonatype.com/repository/maven-snapshots/</url>
        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

Use shapshot version:

<dependency>
    <groupId>ru.vyarus</groupId>
    <artifactId>dropwizard-guicey</artifactId>
    <version>7.2.2-SNAPSHOT</version>
</dependency>
