# Selective Build Maven Plugin

Selective Build Maven Plugin allows you to build and process only modules with changes in it. It is dependent on git client installed on your system.

## Goal `changes` 

This goal is used for selective builds (build only modules with changes). 

It is used in three steps:

1. Configure the plugin in the root POM

2. Run the plugin and put the result into a environment variable

3. Run standard maven build with options from the variable

### Root POM setup

To use this plugin first you should set it up in the root POM like this.

```xml

    ...

    

        ...

        

            

                

                    eu.lundegaard.maven

                    selective-build-maven-plugin

                    0.5.0

                

            

        

        ...

    

    ...

```

### Get params for the build

The `changes` plugin outputs on _stdout_ parameters for the onward build. These parameters are based on current git status and can result into one of the following states:

1. Non-recursive build (build only root project) -- This happens mainly when there are no changes detected

2. Selective build (build only changed modules)

3. Full rebuild -- this happens when there are too much commits or when special files are changed

To obtain params one usually runs something like this:

```bash

MVN_RUN_OPTS=$(mvn -q -N selective-build:changes -Dsource=1234567890ABCDEF -Dtarget=FEDCBA0987654321)

```

The `source` and `target` properties are either commits or branches between which the changes are detected.

### Run selective Maven build

To run the selective build afterwards is simple. Just run something like this:

```bash

mvn $MVN_RUN_OPTS clean verify 

```
