When we use for example the
war command Grails will create files and stores them by default in the project’s working directory. The location of the project working directory can be customized in our
grails-app/conf/BuildConfig.groovy configuration file. We remove the generated files with the Grails
clean command. This command will remove all compiled class files, the WAR file, cached scripts and test reports. But this doesn’t remove all files in the project working directory. For example plugins or a temporary
web.xml file, which are stored in the project working directory are not removed. We must use the
clean-all command to also remove those files from the project working directory completely.
Let’s take a look at the default settings in our
grails-app/conf/BuildConfig.groovy configuration file when we create a new Grails application:
// File: grails-app/conf/BuildConfig.groovy ... grails.project.class.dir = "target/classes" grails.project.test.class.dir = "target/test-classes" grails.project.test.reports.dir = "target/test-reports" grails.project.work.dir = "target/work" ...
After we run the
war command we see the following contents in our
$ grails war | Compiling 10 source files | Compiling 142 source files | Done creating WAR target/cleanCmd-0.1.war $ ls target/ classes cleanCmd-0.1.war stacktrace.log work
Let’s first run the
clean command and check the contents of the
target directory again:
$ grails clean | Application cleaned. $ ls target/ stacktrace.log work
target/work directory still exists. We now run
clean-all and examine the contents of the
$ grails clean-all | Application cleaned. $ ls target/ stacktrace.log
work directory is removed as well.
We can also write our own scripts to for example only remove the generated WAR file with a clean command. With the following script we add the command
clean-war to our application, which will delete the generated WAR file from our project:
// File: scripts/CleanWar.groovy includeTargets << grailsScript("_GrailsClean") setDefaultTarget("cleanWarFile")
We can use the targets
cleanWarFile in our own scripts.

The course demonstrates how to install both Java and the Eclipse IDE and dives into the particulars of programming. The course also explains the fundamentals of Java, from creating simple variables, assigning values, and declaring methods to working with strings, arrays, and subclasses; reading and writing to text files; and implementing object oriented programming concepts. Exercise files are included with the course.
