mavenBuild

This step will install the maven project into the local maven repository.

Description

This step will install the maven project into the local maven repository. It will also prepare jacoco to record the code coverage and supports ci friendly versioning by flattening the pom before installing.

build with depedencies from a private repository

if your build has dependencies from a private repository you can include a project settings xml into the source code repository as below (replace the <url> tag with a valid private repo url). 

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <servers>
    <server>
        <id>private.repo.id</id>
        <username>${env.PIPER_VAULTCREDENTIAL_USERNAME}</username>
        <password>${env.PIPER_VAULTCREDENTIAL_PASSWORD}</password>
    </server>
  </servers>
</settings>
PIPER_VAULTCREDENTIAL_USERNAME and PIPER_VAULTCREDENTIAL_PASSWORD are the username and password for the private repository and are exposed as environment variables that must be present in the environment where the Piper step runs or alternatively can be created using : vault general purpose credentials

include the below <repositories> tag in your pom.xml to reference the <server> and make sure the values in the <id> tags match 

<repositories>
    <repository>
      <id>private.repo.id</id>
      <url>https://private.repo.com/</url>
    </repository>
</repositories>

Ensure the following configuration in the Piper config.yaml to ensure the above settings xml is included and all steps can consume this parameter:

general:
  projectSettingsFile: <path to the above settings.xml>

Usage

We recommend to define values of step parameters via .pipeline/config.yml file.
In this case, calling the step is essentially reduced to defining the step name.
Calling the step can be done either in an orchestrator specific way (e.g. via a Jenkins library step) or on the command line.

Details

altDeploymentRepositoryID

Id for the alternative deployment repository to which the project artifacts should be deployed ( other than those specified in ). This id will be updated in settings.xml and will be used as a flag with DaltDeploymentRepository along with mavenAltDeploymentRepositoryUrl during maven deploy . When no settings.xml is provided a new one is created corresponding with tag
