write a git pre-push hook

active-active git maven

write a pre-push hook

#!/bin/bash
# before push, do unit test
cd app/webapp
mvn clean test

pretty simple.
if you go to .git/hooks, you would find a file pre-push.sample, take it as a reference. then name the above script pre-push, no suffix, put it to .git/hooks folder.

then give permissin:
chmod +x pre-push.

then each time you do push, the unit test would be triggered.

how to distribute this script and enforce it

you can not directly push the .git/hooks. so you need to find some other ways to do it. Here is my step:
- create a folder, such as buildtool in your project, then put the pre-push script there.
- write a Makefile, it would copy the script to .git/hooks, and assign it appropriate permission.
- let maven to call make to build the makefile.

for step 2, here is my Makefile

SHELL = /bin/bash
build : copyfile assignpermission
copyfile :
        if [ -d "../../../.git/hooks" ]; then \
                cp -f pre-push ../../../.git/hooks; \
        fi
assignpermission :
        if [ -e "../../../.git/hooks/pre-push" ]; then \
                chmod +x ../../../.git/hooks/pre-push; \
        fi

notice I use the relative path because the project I'm working on is a module of a bigger project.

for step 3, here is the pom

for the parent pom.xml, I did something like this:

        <pluginManagement>
            <plugins>
            ......
                <plugin>
                    <artifactId>maven-antrun-plugin</artifactId>
                    <version>1.8</version>
                </plugin>

then in the project pom.xml, the change is :

            <plugin>
                <artifactId>maven-antrun-plugin</artifactId>
                <executions>
                    <execution>
                        <id>make</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>run</goal>
                        </goals>
                        <configuration>
                            <target name="make">
                                <exec executable="make" failonerror="true"
                                      dir="${project.basedir}/buildtool"/>
                            </target>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

use maven-antrun-plugin to trigger the make command.

then it is done.

results

then each time when other developer who run mvn clean install, he would see something like this :

[INFO] --- maven-antrun-plugin:1.8:run (make) @ webapp ---
[INFO] Executing tasks
make:
     [exec] if [ -d "../../../.git/hooks" ]; then \
     [exec]                             cp -f pre-push ../../../.git/hooks; \
     [exec]             fi
     [exec] if [ -e "../../../.git/hooks/pre-push" ]; then \
     [exec]                             chmod +x ../../../.git/hooks/pre-push; \
     [exec]             fi
[INFO] Executed tasks

then when they do push, unit test would be triggered:
