Build Status

Overview

Maven doesn't give you detailed information about where your build is taking the most time. This build time extension displays the duration for each goal that is run during your build.

Usage

Put this in your pom.xml to find out why you are slow. By default this will log only to maven debug -X,--debug, however debug is quite noisy, so you can enable output to normal log via the property buildtime.output.log in your pom or via commandline -Dbuildtime.output.log=true.

Capture the results to a CSV file

Thanks to @leonard84 for the contribution. You'll need to set a property to enable this feature. Eventually, we can enhance this functionality to include other output formats. I personally would like to publish the results to an InfluxDb instance.

mvn compile -Dbuildtime.output.csv=true -Dbuildtime.output.csv.file=classes\out.csv

Maven introduced slf4j in version 3.2 which broke this build extension for Maven 3.0 users. Version 2.0+ will work with the latest version of Maven.

Maven 3.3 - Use version 3.0+

With version 3.0.0 we switched to Maven's EventSpy API which increases the compatibility with other tools, e.g. Jenkins which also use this API to instrument Maven. However this requires a different way of loading the extension. This also requires at least Maven 3.3+.

Create the following file <projectroot>/.mvn/extensions.xml with this as content

<?xml version="1.0" encoding="UTF-8"?>
<extensions>
    <extension>
        <groupId>co.leantechniques</groupId>
        <artifactId>maven-buildtime-extension</artifactId>
        <version>3.0.0</version>
    </extension>
</extensions>

Due to MNG-5786 you might need to use Maven 3.3.9 if <projectroot>/.mvn/extensions.xml is not picked up. You can also check the build log for the presence of the string BuildTimeEventSpy is registered. which is logged if the extension was successfully activated.

Maven 3.2 - Use version 2.0+ Deprecated

<build>
    <extensions>
        <extension>
            <groupId>co.leantechniques</groupId>
            <artifactId>maven-buildtime-extension</artifactId>
            <version>2.0.3</version>
        </extension>
    </extensions>
</build>

Maven 3.0 - Use version 1.0 Deprecated

Version 1 works with Maven 3.0. All future improvements and bug fixes will occur on the 2.0 version of this build extension

<build>
    <extensions>
        <extension>
            <groupId>co.leantechniques</groupId>
            <artifactId>maven-buildtime-extension</artifactId>
            <version>1.0.1</version>
        </extension>
    </extensions>
</build>

One-off execution

Instead of modifying the POM you can also perform a one-off execution. In this case you must manually download the extension (only once, before the first execution) and then explicitly provide it as a command line argument:

VERSION=2.0.3
mvn -q dependency:get -Dartifact="co.leantechniques:maven-buildtime-extension:$VERSION"
mvn compile -Dmaven.ext.class.path="$HOME/.m2/repository/co/leantechniques/maven-buildtime-extension/$VERSION/maven-buildtime-extension-$VERSION.jar"

Release Process

Sonatype requires all published components to be signed. These commands prompt for a gpg passphase. (Reminder for me: It is in your password vault)

./mvnw release:prepare

./mvnw release:perform

2018-05-30 Had to add this command to the my console to get it signed:

GPG_TTY=$(tty)
export GPG_TTY
