- 1. An Introduction to Ant Bryan G. Hutchinson preEmptive Solutions, Inc.
- 2. An Introduction to Ant What is Ant? How do you use it? Why would you want to?
- 3. What is Ant? “crawling insect living in colonies: an insect that lives in complex well-organized colonies and is noted for …” Encarta World English Dictionary
- 4. What is Ant? According to Ant’s web site, ant is “ Apache Ant is a Java-based build tool. In theory, it is kind of like Make, but without Make's wrinkles.” I’ve called Ant “Make on Steroids!”
- 5. Make Limitations Shell-based: tied to a particular OS Makefile issues: tab vs. space
- 6. Ant Advantages Platform independent - thanks to Java! XML config files Tasks run by object implementing Task Interface
- 7. How to use Ant Install Ant Get It from the Ant home page Install It (Optional) Build It Check Library Dependancies and Platform-dependant issues
- 8. How to Use Ant Configured using an XML buildfile Buildfile contains one project and at least one target Targets contain Tasks
- 9. Ant Buildfile Projects have three attributes Optional name - name of project Required default - task to perform Optional basedir - base directory used for path calculation <project name=”JavaSig" default="deploy" basedir=".">
- 10. Ant Buildfile A project defines one or more targets A target is a set of tasks to execute The default target is executed unless a target is specified when executing Ant
- 11. Ant Buildfile - Target <target name="deploy" depends="dist"> <!-- Copy jars to the weblogic instance --> <copy preservelastmodified="yes" todir="${deploy_dir}"> <fileset dir="${dist}"> <include name="*.jar"/> <exclude name=”TestClients.jar"/> </fileset> </copy> </target>
- 12. Ant Buildfile - Targets Can depend on other targets Gets executed only once Can determine execution based on a property
- 13. Ant Buildfile - Tasks Code that can be executed Can have multiple attributes Ant includes built-in tasks and optional tasks Can write your own tasks in Java <javac srcdir="${src}" destdir="${build}"> <classpath refid=”compile.class.path"/> </javac>
- 14. Ant Buildfile - Properties Properties can be set for a project Setup using the <property> task Setup in an external properties file Case-sensitive name / value Can be reference in task attributes using “${ propertyName }” System properties and Ant built-in properties available
- 15. Ant Buildfile - Properties <!-- set global properties for this build --> <property name="src" value="src"/> <property name="build" value="build"/> <property name="dist" value="dist"/> <property name="lib" value="lib"/> <property name="archive" value="archive"/> <property name="weblogic.home" value="c:\weblogic"/> <property name="wl_lib" value="${weblogic.home}/myserver/lib"/>
- 16. Ant Buildfile - PatternSets Patterns can be grouped in sets and referenced by id Defined by <patternset> element nested in a FileSet directory-based task stand alone element at target level
- 17. Ant Buildfile - PatternSets <patternset> has the following attributes: includes: list of patterns/files to include includesfile: name of file listing includes excludes: list of patterns/files to exclude excludesfile: name of file listing excludes Can also use nested <include> and <exclude> elements to specify patterns
- 18. Ant Buildfile - FileSets Groups of files Used by many tasks Files are found in a directory tree starting in a base directory and matching any number of PatternSets Can use nested <patternset> elements Also holds an implicit PatternSet
- 19. Ant Buildfile - FileSets <fileset dir="${build}" includesfile="browseQueues.txt"/> <fileset dir="${lib}/resources" includes="**/BrowseQueues.properties"/> <fileset dir="${dist}"> <include name="*.jar"/> <exclude name="GrinderTests.jar"/> <exclude name="SystemTest.jar"/> <exclude name="BrowseQueues.jar"/> </fileset>
