ant and command line arguments and absolute path - ant

All
I am passing a -D build.dir = ~/myhome/build to my ant script and when I echo build.dir it is coming out relative to where the build.xml is such as ./~/myhome/build.
I am using command line argument since I have to override a property defined in a properties file.
Thoughts on this?

Try this code:
<?xml version="1.0" encoding="UTF-8" ?>
<project default="all" basedir=".">
<taskdef resource="net/sf/antcontrib/antcontrib.properties" />
<target name="all">
<echo message="${user.home}" />
<propertyregex property="build.dir"
input="${build.dir}"
regexp="~"
replace="${user.home}"
override="true" />
<echo message="${build.dir}" />
</target>
</project>

my property file seems not to be implemented by build.xml

I have a problem with properties.
here is content of my build.xml file:
<?xml version="1.0" ?>
<project name="default" default="package">
<target name="init">
<mkdir dir="build/classes" />
<mkdir dir="dist" />
</target>
<property file="${basedir}/localproperties"/>
<property name="javac.debug" value="off"/>
<target name="compile" depends="init" description="Compiles JAVA files">
<echo message="Debug: ${javac.debug}"/>
<javac srcdir="src"
destdir="build/classes"
classpathref="compile.classpath"
debug="${javac.debug}"/>
</target>
<path id="compile.classpath">
<fileset dir="lib" includes="*.jar"/>
</path>
</project>
and here is content of my localproperties file:
javac.debug = on
please note that I have saved localproperties as .xml file and put it into the same directory as build.xml
the problem is that it does not work as the output I get is:
Debug: off
clearly it should be:
Debug: on
please advise.
It should be:
<property file="${basedir}/localproperties.xml"/>
There is no extension assumed by the property task. As long as the content follows the key-value convention, it can be any file extension. But it would be confusing to save as .xml. Just save it as localproperties.properties, or simply local.properties.

Configure Sonar for Delphi with sub-modules

I can get Delphi analysis working on single projects, so the plugin works.
I can get Submodules analysis set up as per my previous question but no delphi analysis is performed.
refer to Configuration of build.xml file for Sonar modules with Ant for reference.
If I include the (I believe) required delphi configuration in the master build file it only works if I include the sonar.sources line.
BUT, when I include that line it is attempting to analyse all delphi code and is ignorning the submodules.
How (assuming it can be done) do I configure this to work or do I have to run each project completely separately?

sorting as well as removing duplicacy

<?xml version="1.0"?>
<project name="sortlist11" default="sortlist11">
<taskdef resource="net/sf/antcontrib/antcontrib.properties" />
<property name="my.list" value="z,y,x,w,v,u,t" />
<property name="my.list1" `value="5,3,6,1,8,4,6" `/>
<target name="sortlist11">
<sortlist property="my.sorted.list" value="${my.list}" delimiter="," />
<sortlist property="my.sorted.list1" value="${my.list1}" delimiter="," />
<echo message="${my.sorted.list}" />
<echo message="${my.sorted.list1}" />
</target>
</project>
here second echo print 1,3,4,5,6,6,8 but how can i remove redundancy?
Every language running in JVM via Bean Scripting Framework may be used in ant with full access to the ant api. Here's a solution with Groovy for your problem =
<project>
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy"/>
<property name="my.list" value="z,y,x,w,v,u,t"/>
<property name="my.list1" value="5,3,6,1,8,4,6"/>
<groovy>
properties.'my.sorted.list' = properties.'my.list'.split(',').sort().toString()
properties.'my.sorted.list1' = properties.'my.list1'.split(',').toList().unique().sort().toString()
</groovy>
<echo>
$${my.sorted.list} => ${my.sorted.list}
$${my.sorted.list1} => ${my.sorted.list1}
</echo>
</project>

Retrieve property value from include'd / import'ed project

I am trying to use ant's include or import tasks to use a common build file. I am stuck at retrieving properties from included file.
These are my non-working samples, trying to retrieve "child-property"
Using ant import
parent file
<?xml version="1.0" encoding="UTF-8"?>
<project name="parent" basedir=".">
<import file="child.xml" />
<target name="parent-target">
<antcall target="child-target" />
<echo message="(From Parent) ${child-property}" />
</target>
</project>
child file
<?xml version="1.0" encoding="UTF-8"?>
<project name="child" basedir=".">
<target name="child-target">
<property name="child-property" value="i am child value" />
<echo message="(From Child) ${child-property}" />
</target>
</project>
output
parent-target:
child-target:
[echo] (From Child) i am child value
[echo] (From Parent) ${child-property}
Using ant include
parent file
<project name="parent" basedir=".">
<include file="child.xml" />
<target name="parent-target">
<antcall target="child.child-target" />
<echo message="(From Parent) ${child-property}" />
<echo message="(From Parent2) ${child.child-property}" />
</target>
</project>
child file
same as above
output
parent-target:
child.child-target:
[echo] (From Child) i am child value
[echo] (From Parent) ${child-property}
[echo] (From Parent2) ${child.child-property}
How can I access "child-property" from parent?
When you use the antcall task a new Ant cycle is started for the antcall'ed task - but that doesn't affect the context of the caller:
The called target(s) are run in a new
project; be aware that this means
properties, references, etc. set by
called targets will not persist back
to the calling project.
One way to make your simple example to work would be to change the first parent to:
<target name="parent-target" depends="child-target">
<echo message="(From Parent) ${child-property}" />
</target>
Then the child-target will be executed in the parent context before the parent-target.
But, you may find that there are side affects to running the child task in the context of the parent that you don't want.
It is a different approach but you may use macrodef.
parent.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="parent" basedir=".">
<import file="child.xml"/>
<target name="parent-target">
<child-macro myid="test"/>
<echo message="(From Parent) ${child-property}" />
</target>
child.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="child" basedir=".">
<macrodef name="child-macro">
<attribute name="myid" default=""/>
<sequential>
<property name="child-property" value="i am child value" />
<echo message="(From Child) ${child-property}" />
<echo message="Received params: myId=#{myid}"/>
</sequential>
</macrodef>
</project>
output
parent-target:
[echo] (From Child) i am child value
[echo] Received params: myId=test
[echo] (From Parent) i am child value
Ant-contrib's runtarget task has sufficiently solved my problem. It mignt not be suitable for others since it runs the target in parent's context. Guess there is no "one solution for all" for these kind of problems until Ant officially supports variables.
Parent
<project name="parent" basedir=".">
<!-- insert necessary antcontrib taskdef here-->
<include file="child.xml" />
<target name="parent-target">
<var name="x" value="x"/>
<runtarget target="child.child-target"/>
<echo message="From Parent: ${x}"/>
</target>
</project>
Child
<project name="child" basedir=".">
<property name="pre" value="childpre" />
<target name="child-target">
<var name="x" value="${x}y" />
</target>
</project>
Output
parent-target:
child.child-target:
[echo] From Parent: xy

How to parameterize a path in ANT?

I have the following defined in a file called build-dependencies.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="build-dependencies">
...
<path id="common-jars">
<fileset file="artifacts/project-1/jar/some*.jar" />
<fileset file="artifacts/project-2/jar/someother*.jar" />
</path>
...
</project>
I include it at the top of my build.xml file. Now I need to make the artifacts folder a parameter so it can be changed during execution of different targets.
Having this...
<?xml version="1.0" encoding="UTF-8"?>
<project name="build-dependencies">
...
<path id="common-jars">
<fileset file="${artifacts}/project-1/jar/some*.jar" />
<fileset file="${artifacts}/project-2/jar/someother*.jar" />
</path>
...
</project>
...and defining an "artifacts" property (and changing it) in the target does not work because it seems that the property substitution happens when the path is defined in build-dependencies.xml
How can I solve this? One way I was thinking was to have a parameterized macro and call that before the path is actually used, but that seems not elegant. Something like this:
<macrodef name="create-common-jars">
<attribute name="artifacts"/>
<sequential>
<path id="common-jars">
<fileset file="#{artifacts}/project-1/jar/some*.jar" />
<fileset file="#{artifacts}/project-2/jar/someother*.jar" />
</path>
</sequential>
</macrodef>
EDIT: Ivy and command line parameters are not an option.
You don't want a parameterized path. You want a PatternSet. You can define the patternset at the top-level and then just refer to it in individual targets when you need it. For your example:
<?xml version="1.0" encoding="UTF-8"?>
<project name="build-dependencies">
...
<patternset id="common-jars">
<include name="project-1/jar/some*.jar" />
<include name="project-2/jar/someother*.jar" />
</patternset>
...
<path id="instrumented-jars">
<fileset dir="instrumented">
<patternset refid="common-jars" />
</fileset>
</path>
...
<path id="standard-jars">
<fileset dir="not-instrumented">
<patternset refid="common-jars" />
</fileset>
</path>
...
</project>
I'd recommend using ivy to manage your classpath dependencies. Ivy has a neat concept called configurations that allows you to group collections of artifacts based on their usage.
Here's an adaption from one of my own build files:
<target name="retrieve" description="3rd party dependencies">
<ivy:resolve/>
<ivy:cachepath pathid="build.path" conf="build"/>
<ivy:cachepath pathid="runtime.path" conf="runtime"/>
</target>
The configurations are managed in the ivy.xml file (Would replace your build-dependencies.xml file)
<ivy-module version="2.0">
<info organisation="com.myspotontheweb" module="HelloWorld"/>
<configurations>
<conf name="build" description="jars needed for build" />
<conf name="runtime" extends="build" description="jars needed at runtime" />
</configurations>
<dependencies>
<dependency org="org1" name="project1" rev="1.0" conf="build->default"/>
<dependency org="org2" name="project2" rev="1.0" conf="build->default"/>
<dependency org="org3" name="project3" rev="1.0" conf="runtime->default"/>
<dependency org="org4" name="project4" rev="1.0" conf="runtime->default"/>
</dependencies>
</ivy-module>
The jar artifacts associated with each project would be downloaded and cached automatically from the on-line maven repositories or you can create your own local repository to hold collections of locally owned artifacts.
Lets call your file build.xml. So you execute it by running ant command. In the first case the artifacts names is hardcoded in the property defined on the third line below
<?xml version="1.0" encoding="UTF-8"?>
<project name="build-dependencies">
<property name="artifacts" value="first-value" />
...
<path id="common-jars">
<fileset file="artifacts/project-1/jar/some*.jar" />
<fileset file="artifacts/project-2/jar/someother*.jar" />
</path>
...
</project>
Now when you want to change it and use another value for that artifacts property, we run the script thus
ant -Dartifacts=new-value
This will override the hardcoded artifacts value in build.xml
If working in terms of ant targets you can do something similar, in the target on first line define the property, and if you want to overwrite the default value then pass the property as a parameter when that target is called.
Your comment reminded me of something else. Have your developers create a artifacts-dir-name.xml file. It will have only one line:
<?xml version="1.0" encoding="UTF-8"?>
<project name="artifacts-file">
<property name="artifacts" value="new-value" />
</project>
Now in your build.xml file, before the line where artifacts property is defined, import that file thus:
<import file="artifacts-dir-name.xml" optional="true" />
Now in Eclipse if this file exists, then the property is read from it and artifacts is set to "new-value", else the property is read from build.xml and is set to "first-value". All the developers need to do is to ensure artifacts-dir-name.xml file exists in that directory. This can run within Eclipse too.
is using environment variables an option (if they are set when eclipse is launched they will be picked up)? If so, have each one set ARTIFACTS and this should work:
<?xml version="1.0" encoding="UTF-8"?>
<project name="build-dependencies">
<property environment="env"/>
<path id="common-jars">
<fileset file="${env.ARTIFACTS}/project-1/jar/some*.jar" />
<fileset file="${env.ARTIFACTS}/project-2/jar/someother*.jar" />
</path>
</project>
OK, I think there is no other obvious way for me to do what I am trying to do, except use a macro that takes a parameter and creates the path with the appropriate artifacts folder.
To give a bit of context, why I was trying to what I wanted is to have "instrumented" and "not-instrumented" artifacts in separate folders. And in my "targets" I could just vary the artifacts mode. So what I do now is I have a macro: <initialise-build-settings artifacts-mode="instrumented" /> that sets up all the paths and other variables.
Thanks for your answers guys.
You can do this with different dependencies:
setpath.xml:
<project name="setpath">
<target name="setCommonJars">
<path id="common-jars">
<fileset file="${param1}/some*.jar" />
<fileset file="${param1}/someother*.jar" />
</path>
</target>
</project>
build.xml:
<project name="Test path" basedir=".">
<import file="./setpath.xml" />
<target name="buildT1" depends="setT1,setCommonJars">
<property name="jar-str" refid="common-jars" />
<echo message="buildT1: ${jar-str}" />
</target>
<target name="buildT2" depends="setT2,setCommonJars">
<property name="jar-str" refid="common-jars" />
<echo message="buildT2: ${jar-str}" />
</target>
<target name="setT1">
<property name="param1" value="t1" />
</target>
<target name="setT2">
<property name="param1" value="t2" />
</target>
</project>
If you call target buildT1 then the t1 directory will be used, if you call buildT2 then the t2 directory will be used.
