Dependency History Maven

This project is a small library that knows how to retrieve the release history for a package that is published in a Maven repository.

Usage

Gradle

dependencies {
    implementation("com.corgibytes:dependency-history-maven:2.0.+")
}

Maven

<dependencies>
    <dependency>
        <groupId>com.corgibytes</groupId>
        <artifactId>dependency-history-maven</artifactId>
        <version>[2.0.0,)</version>
    </dependency>
</dependencies>

Example

val service = ReleaseHistoryService()

val actualResults = service.getVersionHistory("org.apache.maven", "apache-maven")

println(actualResults["2.0.10"])
// outputs: 2009-02-10T02:57:59Z

Changing the Maven repository

By default the ReleaseHistoryService uses Maven Central to retrieve release history information. To use another repository pass the value into the constructor.

For example, here's how to create an instance of the service that communicates with the repository used by the Spring project.

val service = ReleaseHistoryService("https://repo.spring.io/artifactory/release/")

⚠️ When you specify an alternative repository, Maven Central will still be contacted to retrieve the information that it has for the package in question. This works around issues with some Maven repository proxies not preserving release history information. For each package version that is queried, the oldest date will be used.

About
