Question

I think I am misunderstanding something import with the maven-release-plugin. I am able to do mvn release:prepare successfully but mvn release:perform always fails.

Maven version:

Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
Maven home: C:\Program Files\apache-maven-3.0.3
Java version: 1.6.0_25, vendor: Sun Microsystems Inc.
Java home: C:\Program Files\Java\jdk1.6.0_25\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

My POM.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

The error that I am getting when I run mvn release:perform is:

[INFO] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plug
in:2.5:deploy (default-deploy) on project cats: Failed to deploy artifacts: Coul
d not find artifact com.animals:cats:jar:0.0.1 in repo (https://my-repo-url)

I am really at a loss as to why this is happening. I have tried setting up a separate repository just for release:perform but no luck, I have tried using the same repository for release:prepare and release:perform, I have tried omitting the <distributionManagement/> section. I have also tried changing the preparetion goals in the maven-release-plugin to be clean install. All of these are solutions that other stackoverflow users have found to be helpful but unfortunately they are not working in this case.

Is the problem in my pom.xml configuration, or perhaps something else? If there is any other information that you might need please let me know! I appreciate your time and help!

EDIT: This is a very simple project with no modules. 0.0.1-SNAPSHOT is the version I have currently defined, and all other Maven goals seem to be working with no issue. I am not using any profile.

EDIT I have edited the question to include my entire POM.xml.

Answer 1

Fixed the issue. The problem was indeed with my repositories and not the pom.xml.
