How to update the ant build script (build.xml) to get the latest code from the repository?

[Keerthi Kumar]

Hi all,

Apart from development in java/j2ee, I am also being involved in build & deployment process. Can anyone please help me out to update the build.xml file to get the latest code from the repository and then compile and deploy the same. If I am able to achieve this almost I can save a time of 20 minutes, which takes to get the latest code from the repository. I am using SVN repository.

Please do the needful. Thanks in advance.

Hi,

Thanks a lot for your kind reply. Also please let me know how to update the build.xml to get a version details after each successful build. What code snippet needs to be added in the build.xml to get the latest version details. Please do the needful.

Hi all,

I have added the following piece of code in my build.xml

<!-- this target will automatically create an html file with
	    an incremented build number and version number-->
	    <target name="versionInfo" depends="war" >
	        <propertyfile
	            file="version.properties" comment="Build version info">
	            <entry key="buildDate" type="date" value="now"/>
	            <entry key="buildNum" default="0" type="int" operation="+" value="1"/>
	        </propertyfile>
	        <copy file="${version.dir}/version.html" tofile="${version.dir}/version.html" overwrite="true" />
	        <replace
	            file="${version.dir}/version.html"
	            value="value not found in version.properties"
	            propertyFile="version.properties">
	            <replacefilter
	                token="@buildDate@"
	                property="buildDate"/>
	            <replacefilter
	                token="@buildNum@"
	                property="buildNum"/>
	        </replace>
	    </target>

And the following code in version.properties

#My properties
# A string value
akey=avalue

# The following is a counter, which will be incremented by 1 for
# each time the build is run.
anint=2

buildDate=2005/08/31 13\:47
buildNum=0014
formated.date=243 13\:47

And I am writing the output to a html file. But still not able to get the build number. so please help me out to resolve the same.

Please use code tags - they make source code readable. I fixed your post this time.

What about using filtering when copying??

<filter filtersfile="version.properties" />
<copy file="${version.dir}/versionTemp.html" tofile="${version.dir}/version.html" overwrite="true" filtering="true" />

and remember to rename the version.html - because you can't do a self-copy (the filter task will be skipped)
