A nice summary on Stack Overflow

I use the Maven properties plugin quite a bit, so I created a bash function for it.

In .bashrc add these lines:
function mvnr {
mvn properties:read-project-properties "$@"
}

I enjoy using lib-notify, but I forget to use it a lot, so I redefined the execution for mvn to add it automatically. For good measure, I did the same to ant and gradle.

This is all done on Ubuntu 12.04 with .bashrc in the home directory, but it should work for any unix based os that has the lib-notify library, the syntax may be slightly different is all.

First we need to comment out the existing alert alias.
# Add an "alert" alias for long running commands. Use like so:
# sleep 10; alert
#alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'

Now we transform it into a function and add an additional step, play a sound.
function alert {
notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e 's/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//')"
play -q /path/to/a/sound/file.wav
}

Now that the alert alias is a function, we can reuse it in the mvnr function we added above
function mvnr {
mvn properties:read-project-properties "$@"
# if using the mvn function below, comment the next line to avoid getting two notifications
alert
}

Let's spread that alert functionality across maven, ant and gradle. We need to specify the full path to the executable since we are redefining the "alias", else we'll get an infinite loop.
function mvn {
$MAVEN_HOME/bin/mvn "$@"
alert
}
function ant {
$ANT_HOME/bin/ant "$@"
alert
}
function gradle {
$GRADLE_HOME/bin/gradle "$@"
alert
}

I heartily recommend taking advantage of lib-notify for any build system: maven, gradle, ant, make, rake, etc.

If you follow this earlier post, you will be able to have groovy tests, but I omitted the code that would allow you to compile groovy along with your java.

Adding these two lines will allow you to call java from groovy and vice versa. You don't have to worry about problems compiling one before the other because the groovy compiler will go through and generate stubs which will make that possible.

Add the the generateStubs and compile line to the preexisting section from the post above:

<goals>
<goal>generateStubs</goal>
<goal>compile</goal>
<goal>generateTestStubs</goal>
<goal>testCompile</goal>
</goals>

It really just comes down to using the form tags in Spring. The following is used within select.tagx as part of allowing a null value to be chosen.

<spring:bind path="${field}">
  <c:set value="${status.value}" var="valSelected"/>
</spring:bind>
