# Maven BuildTime Profiler
[](http://www.apache.org/licenses/)
[](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.soebes.maven.extensions%22%20a%3A%22maven-buildtime-profiler%22)
Often you have the problem that in large builds, you need to find
where time is consumed.
This is an [EventSpy][1] implementation which collects all the information of
all phases and mojo executions and make a summarization output at the end of
the build.
## Minimum Requirements
This extension will only work for Maven 3.3.1+ (>= 0.5.0) and requires JDK8+
## Configuration
If you like to use this extension for Maven you have to define the following `.mvn/extensions.xml` file:
``` xml
com.soebes.maven.extensions
maven-buildtime-profiler
0.5.0
```
If you don't like to add the `.mvn/extensions.xml` to your project you can also go via command line like this:
```
mvn verify -Dmaven.ext.class.path=$HOME/.m2/repository/com/soebes/maven/extensions/maven-buildtime-profiles/0.5.0/maven-buildtime-profiler-0.5.0.jar
```
The download from Maven Central will be done by Maven itself.
### Deactivation
If you like to deactivate the extension without removing the `.mvn/extensions.xml` file this can easily achieved,
by adding the following to your command line (system property):
```
mvn -Dmaven-build-time-profiler.disabled verify
```
That means only the following lines will appear in your console output:
```text
[INFO] Maven Build Time Profiler started. (Version 0.5.0)
[INFO] Maven Build Time Profiler deactivated.
```
That will give you the explicit hint that the extension has been deactivated.
Hint: It is **NOT** possible to deactivate the extension via properties from your `pom.xml` file!
## Example Output
Here's an example of what the output will look like:

Most important might be in this relationship that you will get also information about the
time taken to install artifacts:
```

And much more important are things like the time for the deployment:
