# Java Dependency Updates
|
|
|
|
Renovate can update Gradle and Maven dependencies.
|
|
This includes libraries and plugins.
|
|
|
|
## Gradle
|
|
|
|
Renovate detects versions that are specified in a string `'group:artifact:version'` and those specified in a map `(group:groupName, name:ArtifactName, version:Version)`.
|
|
|
|
### File Support
|
|
|
|
Renovate can update `build.gradle`/`build.gradle.kts` files in the root of the repository.
|
|
It also updates any `*.gradle`/`*.gradle.kts` files in a subdirectory as multi-project configurations.
|
|
|
|
Renovate does not support:
|
|
|
|
- Projects which do not have either a `build.gradle` or `build.gradle.kts` in the repository root
|
|
- Android projects that require extra configuration to run (e.g. setting the Android SDK)
|
|
- Gradle versions prior to version 5.0.
|
|
|
|
### How It Works
|
|
|
|
Renovate uses a plugin to search and extract versions from projects.
|
|
Once the Gradle plugin has detected the dependencies, lookups and updating will be performed like usual with datasources and direct patching of files.
|
|
|
|
## Maven
|
|
|
|
Renovate can update dependency versions found in Maven `pom.xml` files.
|
|
|
|
### File Support
|
|
|
|
Renovate will search repositories for all `pom.xml` files and processes them independently.
|
|
|
|
### Custom registry support, and authentication
|
|
|
|
Here is an example configuration to work with custom Artifactory servers using authentication:
|
|
|
|
```json
|
|
{
|
|
"hostRules": [
|
|
{
|
|
"hostType": "maven",
|
|
"baseUrl": "https://artifactoryurl1/",
|
|
"username": "artifactoryusername",
|
|
"password": "artifactorypassword"
|
|
},
|
|
{
|
|
"hostType": "maven",
|
|
"baseUrl": "https://artifactoryurl2/",
|
|
"username": "artifactoryusername",
|
|
"password": "artifactorypassword"
|
|
}
|
|
],
|
|
"packageRules": [
|
|
{
|
|
"managers": ["maven"],
|
|
"registryUrls": ["https://artifactoryurl1/", "https://artifactoryurl2/"]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
In the above config, the custom registry URLs are defined using a package rule, and the username/passwords are set using a host rule each.
