Question

i have list of 10 properties file say 1.properties , 2 .pro ....10.properties
and another file called total.properties which has all the file properties names .
now the problem is print all file contents which are mentioned in total.properies files
Using ant script.
Eg:
1.properties
name:rajesh
languesknown:en,sp
2.properties
name:kumar
languesknown:en,fr,wd
total.properties
numbers: 1,2
output:
name:rajesh
languesknown:en,sp
name:kumar
languesknown:en,fr,wd
USing ant script.
i tried by
but everytime its printing first record i.e 1.properties but its iterating twice depends on no of contents in total properties . so could any one help on this ?

Answer 1

ANT is not a scripting language. Best way to do this is embed a scripting language. The following example uses Groovy
Example
├── build.xml
└── src
├── 10.properties
├── 1.properties
├── 2.properties
├── 3.properties
├── 4.properties
├── 5.properties
├── 6.properties
├── 7.properties
├── 8.properties
├── 9.properties
└── total.properties
build.xml
<project name="demo" default="print-properties">
<target name="bootstrap">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/groovy-all.jar" src="http://search.maven.org/remotecontent?filepath=org/codehaus/groovy/groovy-all/2.1.7/groovy-all-2.1.7.jar"/>
</target>
<target name="print-properties">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy"/>
<groovy>
new File("src/total.properties").eachLine {
def props = new File("src/${it}")
println props.name
println props.text
}
</groovy>
</target>
</project>
Notes
The "bootstrap" target installs the groovy task jar
The script reads each line of the "total.properties" file and then prints the name and contents of each filename found.
