the lines below are the start of my ant build file and when i try and implemnet sonar with it it shows following error.
The value of attribute "xmlns:sonar" associated with an element type "project" must not contain the '<' character.
<project name="DokLink" default="all" basedir="." xmlns:sonar="antlib:org.sonar.ant>

You have submitted an invalid XML file to ANT. You're missing an end quote around the Sonar URI:
$ xmllint build.xml
..
..
build.xml:3: namespace error : xmlns:sonar: 'antlib:org.sonar.ant> ' is not a valid URI

The following is a corrected XML file:
<project name="DokLink" default="all" basedir="." xmlns:sonar="antlib:org.sonar.ant">

I have latest Jenkins running on Windows 2003 server.
Under, manage Jenkins:
I have IBM JDK set
I have ant: org.apache.ant_1.7.1.v20100518-1145 set as ant home
I have Jenkins AntExec plug in installed.
I have ant-contrib-0.6.jar inside anthome/lib.
I created a job, and added a build step, Execute Apache Ant, and I have this:
<echo> java home = ${JAVA_HOME}</echo>
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
<project name="Test">
<description> Sample bulid file </description>
<target name="first">
<echo message="The first five letters of the alphabet are:"/>
<antcontrib:for list="a,b,c,d,e" param="letter">
<sequential>
<echo>Letter #{letter}</echo>
</sequential>
</antcontrib:for>
</target>
</project>
when I run build, it fails.
antexec_build.xml:
[echo] ant home = ${ANT_HOME}
[echo] java home = ${JAVA_HOME}
BUILD FAILED
C:\Program Files (x86)\Jenkins\jobs\MCSOWelcome\workspace\antexec_build.xml:13: Problem: failed to create task or type project

I have tried many different things, no luck. Please suggest
AntExec comes bundled with AntContrib. You do not need to add or define it. On the contrary, to disable it, you need to open 2 Advanced... dialogs before you get the option.
What you need to do though, is use antcontrib namespace.
For example, to use for, type:
<antcontrib:for>
I ran into the same problem (I got the same error message: Problem: failed to create task or type project), although I didn't use <antcontrib:for> tag.
If you type some code to the Script source field at the Project configuration > Execute Apache Ant, the plugin doesn't use it as an entire Ant script file, but it inserts into a template script. It appears if you choose to keep the buildfile (Advanced view at Execute Ant Build step). In this case the generated antexec_build.xml Ant script will not be deleted from the Workspace of the Project after the build.
The issue is reproducable with this simple script typed in Script source:
<project>
</project>
The generated antexec_build.xml:
<?xml version="1.0" encoding="utf-8"?>
<project default="antexec_build.xml" xmlns:antcontrib="antlib:net.sf.antcontrib" basedir=".">
<!-- Read additional properties -->
<property file="antexec_build.xml.properties"/>
<!-- Make environment variables accesible via ${env.VARIABLE} by default -->
<property environment="env"/>
<target name="antexec_build.xml">
<!-- Default target entered in the first textarea - begin -->
<project>
</project>
<!-- Default target entered in the first textarea - end -->
</target>
</project>
So that, a solution would be that only include the Ant script that you intend to insert into the <target></target> tag.
Let me first provide the background of the problem I'm facing.
I have a directory structure as below.
c:\myDirectory
c:\myDirectory\Project1
c:\myDirectory\Scripts
Under the c:\myDirectory\Scripts there is a script that download the source code (from svn) and creates the c:\myDirectory\Project1 directory.
I have another ant scripts ( c:\myDirectory\Scripts**compile-source.xml ) that compiles the Project1
from an ant script build.xml that is downloaded to c:\myDirectory\Project1
Snippet for c:\myDirectory\Scripts\compile-source.xml
<project name="compile" default="buildAll" basedir=".">
<property file=".\build.properties">
</property>
.......
<import file="${project.home.path}/${project.name}/build.xml"/>
<target name="buildAll">
<antcall target="jar-pack"/>
</target>
</project>
Snippet for c:\myDirectory\Project1\build.xml.
<project name="CommonFeatures" default="jar-pack" basedir=".">
<description>
A build file for the Common Features project
</description>
....
</project>
Note that the basedir for the project is set as "." for both the above ant scripts.
When I execute the script c:\myDirectory\Scripts\compile-source.xml from the c:\myDirectory\Scripts directory the target "jar-pack" present in the c:\myDirectory\Project1\build.xml gets executed.
However, the problem is that basedir attribude in build.xml ( basedir="." ) is the current working directory and in this case its c:\myDirectory\Scripts. Hence the script build.xml errors out since the basedir for build.xml is expected to be c:\myDirectory\Project1. The build.xml script would have worked, if basedir="." were set to "c:\myDirectory\Project1", but unfortunately build.xml file comes from the source code that is downloaded and I'm unable to edit.
So here's my question, Is it possible to do any of the following.
Override the value of the attribude basedir="." in build.xml when the is done in c:\myDirectory\Scripts\compile-source.xml ?
Is it possible to change the basedir in build.xml by any other mechanism so that the script c:\myDirectory\Project1\build.xml is executed under directory c:\myDirectory\Project1 ?
Any other way to resolve this issue?
Any help from Ant experts to overcome this issue is highly appreciated.
You can update basedir using subant task. Check this answer
Create the following build.xml file (assuming it is in Z:/any/folder):
<?xml version="1.0" encoding="UTF-8"?>
<project name="project">
<target name="mytarget">
<subant target="debug">
<property name="basedir" value="X:/any/dir/with/project"/>
<fileset dir="Y:/any/folder/with" includes="build.xml"/>
</subant>
</target>
</project>
The you can execute ant mytarget from Z:/any/folder
You can specifically reference the location of your build file, which is described in this stack overflow thread. This would allow you to get and use the directory your build file resides in as a reference point.
For your case the usage of the subant or ant tasks may be better suited, but nevertheless...
You can (but you should know/consider the side-effects!) extend ant with the common ant-contrib task definitions and use the var task which is able to override properties. Make sure to use the latest version (> 1.0b3).
<!-- adjust to your path and include it somewhere at the beginning of your project file -->
<taskdef resource="net/sf/antcontrib/antlib.xml" classpath="lib/ant-contrib-1.0b3.jar" />
<!-- works e.g. for basedir = /foo/bar to update it to /foo/bar/.. ~ /foo -->
<var name="basedir" value="${basedir}/.." />
update: but one has to be careful, because this does not change . (current working directory) (so <property name="x" location="tmp" /> would be relative to . and not to basedir anymore ; update: setting basedir outside of ant or via <project basedir= also sets . to basedir!). Here is some test target proving the effect on both:
<target name="tst.dummy.basedir-override">
<!-- example output:
tst.dummy.basedir-override:
[echo] basedir before: basedir=D:\tst, '.'=D:\tst\.
[echo] updating it via 'var' to '..'
[echo] basedir now: basedir=D:\tst/.., '.'=D:\tst\.
-->
<property name="cur" location="." /> <!-- makes the relative path absolute -->
<echo message="basedir before: basedir=${basedir}, '.'=${cur}" />
<echo message="updating it via 'var' to '..'" />
<var name="basedir" value="${basedir}/.." />
<property name="cur2" location="." /> <!-- makes the relative path absolute -->
<echo message="basedir now: basedir=${basedir}, '.'=${cur2}" />
</target>
According to the man page of make, -n option does the following job:
Print the commands that would be executed, but do not execute them.
I am looking for an option which acts the same in Apache Ant.
Horrific, but here it is. We can hack the targets at runtime using some code inside a <script> tag*. The code in do-dry-run below sets an unless attribute on each of your targets, and then sets that property so that none of them executes. Ant still prints out the names of targets that are not executed because of an unless attribute.
*(JavaScript script tags seem to be supported in Ant 1.8+ using the Oracle, OpenJDK and IBM versions of Java.)
<?xml version="1.0" encoding="UTF-8"?>
<project default="build">
<target name="targetA"/>
<target name="targetB" depends="targetA">
<echo message="DON'T RUN ME"/>
</target>
<target name="targetC" depends="targetB"/>
<target name="build" depends="targetB"/>
<target name="dry-run">
<do-dry-run target="build"/>
</target>
<macrodef name="do-dry-run">
<attribute name="target"/>
<sequential>
<script language="javascript"><![CDATA[
var targs = project.getTargets().elements();
while( targs.hasMoreElements() ) {
var targ = targs.nextElement();
targ.setUnless( "DRY.RUN" );
}
project.setProperty( "DRY.RUN", "1" );
project.executeTarget( "#{target}" );
]]></script>
</sequential>
</macrodef>
</project>
When I run this normally, the echo happens:
$ ant
Buildfile: build.xml
targetA:
targetB:
[echo] DON'T RUN ME
build:
BUILD SUCCESSFUL
Total time: 0 seconds
But when I run dry-run, it doesn't:
$ ant dry-run
Buildfile: build.xml
dry-run:
targetA:
targetB:
build:
BUILD SUCCESSFUL
Total time: 0 seconds
Ant has no dry-run option as make or maven have. But you could run the ant file step by step it in debugging mode under eclipse.
No I belive. There is no such way by default in Ant. And many unstisfying attempts you would find on google. But I have searched once and was unsuccessful.
It would be a useful feature, but not easily implemented.
Make and ANT are architecturally quite different. ANT doesn't run external OS commands, instead, most ANT "tasks" execute within the same Java thread.
It would be possible to emulate a "dry run" as follows:
<project name="Dry run" default="step3">
<target name="step1" unless="dry.run">
<echo>1) hello world</echo>
</target>
<target name="step2" depends="step1" unless="dry.run">
<echo>2) hello world</echo>
</target>
<target name="step3" depends="step2" unless="dry.run">
<echo>3) hello world</echo>
</target>
</project>
Running ANT as follows will print the target name but won't execute the enclosed tasks:
$ ant -Ddry.run=1
Buildfile: build.xml
step1:
step2:
step3:
BUILD SUCCESSFUL
Total time: 0 seconds
Create a special target in your buildscript that does some echoing only i.e. to check whether properties, path .. are resolved correctly.
see https://stackoverflow.com/a/6724412/130683 for a similar question answered.
For checking the details of your ant installation use ant -diagnostics
here i have one bat file
test.bat ->
#echo off
echo this is piyush
pause
dir c:\
another file is xml(create file .xml) file for creating two text files
my question is that how can i execute xml file in bat file to creating two text file.
Createfile.xml ->
<?xml version="1.0" ?>
<project name="piyush" default="Create_XMLfile">
<target name="Create_XMLfile">
<echo file="peak1.xml" message="This is creation of the peak1"/>
<echo file="peak1.xml" message="This is creation of the peak1"/>
</target>
</project>
That looks like an ant build script.
If you have ant installed, you could try ant -buildfile Createfile.xml.
I'm trying to use the -lib option to specify a directory containing Ant tasks. But they're not loading. For example:
$ ant -lib /path/to/libraries
Buildfile: build.xml
BUILD FAILED
/path/build.xml:3: taskdef class com.oopsconsultancy.xmltask.ant.XmlTask cannot be found
The build file contains:
<project name="test">
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask" />
</project>
This is failing on RHEL5, but the exact same thing works on several other operating systems that I've tried.
When I add the --execdebug flag, I get this:
exec "/usr/local/jdk1.6.0_20/bin/java" -classpath "/usr/share/java/ant.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/jaxp_parser_impl.jar:/usr/share/java/xml-commons-apis.jar:/usr/local/jdk1.6.0_20/lib/tools.jar" -Dant.home="/usr/share/ant" -Dant.library.dir="/usr/share/ant/lib" org.apache.tools.ant.launch.Launcher -cp "" "-lib" "lib"
Any ideas?
Others seem to have the same problem on RHEL.
One workaround suggested here is to set your jar in the taskdef like so
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"
classpath="xmltask.jar"/>
