# Java Dependency Updates
|
|
|
|
Renovate can update the version used in Gradle and Maven projects. This includes libraries and plugins.
|
|
|
|
## Gradle
|
|
|
|
Renovate detects versions specified as string `'group:artifact:version'` and as a map `(group:groupName, name:ArtifactName, version:Version)`.
|
|
|
|
### File Support
|
|
|
|
Renovate can update `build.gradle` files in the root of the repository and any `*.gradle` file inside any subdirectory as multi-project configurations.
|
|
|
|
Renovate does not support:
|
|
|
|
- Projects without a `build.gradle` file in the root of the repository.
|
|
- Android projects that requires extra configuration to run. (e.g. setting the android SDK)
|
|
|
|
### How It Works
|
|
|
|
Renovate uses a plugin to search and extract versions from projects. They are then looked up using Maven datasources and patched into PRs the usual way.
|
|
|
|
It is recommended to use `gitFs` with Gradle, which is not the default setting for GitHub and GitLab. Enabling `gitFs` means that Renovate performs a shallow clone of the repository in order to get access to all the source files necessary, regardless of their name.
|
|
|
|
## Maven
|
|
|
|
Renovate can update dependency versions found in Maven `pom.xml` files.
|
|
|
|
### File Support
|
|
|
|
Renovate will search repositories for all files named `pom.xml` and then process them independently.
|
|
|
|
### Custom registry support, and authentication
|
|
|
|
Here is an example configuration to work with custom Artifactory servers using authentication:
|
|
|
|
```
|
|
{
|
|
"maven": {
|
|
"enabled": true
|
|
},
|
|
"hostRules": [{
|
|
"platform": "maven",
|
|
"endpoint": "https://artifactoryurl1/",
|
|
"username": "artifactoryusername",
|
|
"password": "artifactorypassword"
|
|
}, {
|
|
"platform": "maven",
|
|
"endpoint": "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.
