I am trying to execute the class file in a jar through ant script. I ran the command through CMD it worked fine
Command is like :-
java com.CodeReview -p “<Project Path>”
I tried to run this command through the ant script
<target name="build">
<java fork="true" failonerror="yes" classname="com.CodeReview">
<arg line="-p"/>
<arg line="D:\Test"/>
</java>
</target>
It is giving me error
build:
[java] Error: Could not find or load main class com.CodeReview
but through command line it is working and no issue with classpath. Do I need to set classpath in script also.
You are missing the classpath within your java task:
<classpath>
<pathelement location="yourjar.jar"/>
<pathelement path="${java.class.path}"/>
</classpath>

I need to generate files from .avsc file (avro) in ANT build. I'm not sure what plugin should I use for this. I tried with xjc.XJC2Task for generating the files but it seem to not work. Can some one suggest what plugin / class should I use to generate the files from avro schema in ANT ?
Tried with xjc:
<target name="generate" description="generate">
<mkdir dir="generated" />
<taskdef name="xjc" classname="com.sun.tools.xjc.XJC2Task" classpathref="classpath"/>
<xjc destdir="generated">
<schema dir="setup/kafka" includes="*.avsc" />
</xjc>
</target>
Error:
generate:
[xjc] Consider using <depends>/<produces> so that XJC won't do unnecessary compilation
[xjc] Compiling file:/D:/2019/My-workspace/my-project/setup/kafka/Sample.avsc
[xjc] [ERROR] Content is not allowed in prolog.
[xjc] line 1 of file:/D:/2019/My-workspace/my-project/setup/kafka/Sample.avsc
[xjc] failure in the XJC task. Use the Ant -verbose switch for more details
Used java jar command to compile the avro-tools jar . it worked.
<target name="run-avro">
<java jar="lib/avro-tools-1.10.1.jar" fork="true">
<arg line="compile schema"/>
<arg file="avrolocation/Sample.avsc"/>
<arg file="generated/"/>
</java>
</target>
I'm currently running an exec task in my build like this:
<target name="bar">
<exec executable="ant">
<arg value="-f"/>
<arg value="/path/to/my/build.xml"/>
<arg value="-lib"/>
<arg value="/path/to/my/libs"/>
</exec>
</target>
I don't really like it and want to replace the exec task with an ant task:
<target name="bar">
<ant antfile="/path/to/my/build.xml"/>
</target>
However, I don't know how to specify the lib directory in this case. Is this possible somehow?
What are you trying to achieve, by launching ANT from within ANT in this manner?
For example if you need custom ANT extensions, the path to these jars can be specified at runtime within the code as follows:
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="${lib.dir}/ant-contrib-0.3.jar"/>
</classpath>
</taskdef>
Better again, you could integrate a dependency management system like Apache ivy to manage 3rd party jar dependencies.
You can call ant script inside an ant script like below.
If you use the attribute inheritrefs="true" any Ids that are set in the parent build script will be passed to child build script as well.
Eg:
<ant antfile="subbuild.xml" inheritrefs="true"/>
I am using Apache Ant for my builds. I have some composer scripts belonging to several vendors in vendor/bin folder. I have added this folder to the system path and if I run the commands on my command window in works but in the build file i get an error.
Is there anything I should be doing differently? Before is an example:
<?xml version="1.0" encoding="UTF-8"?>
<project name="MyProject" default="build" basedir=".">
<target name="phpcpd" description="Find duplicate code using PHPCPD">
<exec executable="phpcpd">
<arg value="--version" />
</exec>
</target>
</project>'
I get this when I run ant phpcpd
phpcpd:

But phpcpd --version works on command prompt
ANT is not aware where phpcpd is as it doesn't share path with your Command Promt.
One way around it is to create a .bat file to run phpcpd
Create a phpcpd.bat with the following:
#echo off
phpcpd --version
Your build scripts to be updated from :
<exec executable="phpcpd">
<arg value="--version" />
</exec>
To: <exec executable="phpcpd.bat"/>
Above assumed with Windows Command Promt
My solution was to use the .phar files of the scripts. That way, the build file became platform independent to a large extent. So
<target name="phpcpd" description="Find duplicate code using PHPCPD">
<exec executable="phpcpd">
<arg value="--version" />
</exec>
</target>
Became:
<target name="phpcpd" description="Find duplicate code using PHPCPD">
<exec executable="php">
<arg value="${phpcpd}" />
<arg value="--version" />
</exec>
</target>
Where ${phpcpd} is the path to the phar file
I'm using absolute paths and a configurable executable.properties like this:
build.xml
<project name="build">
<property file="executable.properties" />
<target name="run-phpcd" unless="${phpcpd.skip}">
<exec executable="${phpcpd.executable}"><!-- .. --></exec>
</target>
</project>
executable.dist.properties
phpcpd.skip = no
#phpcpd.executable = C:\path\to\phpcpd.bat
phpcpd.executable = /path/to/phpcpd.sh
Both files can be committed to your VCS, for usage copy the template file (*.dist.properties) and rename it to executable.properties. Add this file to the ignore list of your VCS.
Currently trying to get JSCover to exclude js files that are used as libraries. I have a set of ant scripts below which will
start the JSCover server
Run & Generate Json report
Stop the server
Finally, i have a shell command to convert the Json file to LCov so that i can use it with sonarqube. I also get coverage in jscoverage.html but it includes every file under web/ which is something i do not want. Image below
Ant scripts below:
<target name="jstest-start">
<java jar=".../JSCover.jar" fork="true" spawn="true">
<arg value="-ws"/>
<arg value="--report-dir=coverage"/>
<arg value="--document-root=web"/>
<arg value="--port=8082"/>
<!-- Aim is to exclude folder js under web/ as it contains libraries, not source code. Currently does not work -->
<arg value="--no-instrument=web/js/"/>
<arg value="--no-instrument=js/"/>
</java>
<waitfor maxwait="5" maxwaitunit="second" checkevery="250" checkeveryunit="millisecond" timeoutproperty="failed">
<http url="http://localhost:8082/jscoverage.html"/>
</waitfor>
<fail if="failed"/>
</target>
<target name="jstest-run">
<exec dir="/usr/local/CI/phantomjs/bin/" executable="phantomjs" failonerror="true">
<arg line=".../run-jscover-qunit.js http://localhost:8082/index.html"/>
</exec>
</target>
<target name="jstest-stop">
<get src="http://localhost:8082/stop" dest="stop.txt" />
</target>
<target name="jstest" description="Run javascript tests">
<antcall target="jstest-start"/>
<antcall target="jstest-run"/>
<antcall target="jstest-stop"/>
</target>
My folder structure is:
And finally, my sonar standalone analysis settings:
So, what seems to be happening is that JSCover is recursively reading for all js files and i cannot prevent that from sonar or ant.
Can anyone shed some light?
<arg value="--no-instrument=/js/"/>
should work, and to remove the test itself,
<arg value="--no-instrument=/test/"/>
The paths are as seen by the web-server, so the 'web' prefix in:
<arg value="--no-instrument=web/js/"/>
has no effect.
i have resolved my own issue by correcting the shell command which generates an LCOV report.
java -cp JSCover.jar jscover.report.Main --format=LCOV /usr/local/CI/jenkins/workspace/PhantomJS/coverage/phantom/ /usr/local/CI/jenkins/workspace/PhantomJS/web/
Prior to this, the SRC-DIR and REPORT-DIR were the same which was an error on my part. As far as i can understand, SRC-DIR should point to the source folder and REPORT-DIR should point to where the lcov file exists.
I hope this helps someone
I have a small program that displays some database tables. The program has a class with a main() method. I have an ant script that builds and runs the program.
The ant script is able to build the program and runs its tests but not run it. When i run it I get the following error:
[java] Could not find com.my.MyProgram. Make sure you have it in your classpath
[java] at org.apache.tools.ant.taskdefs.ExecuteJava.execute(ExecuteJava.java:138)
The issue here is that my java task target is not finding my classpath. I have printed my classpath and it has all the necessary jars and classes.
Here is part of my build.xml:
<path id="classpath">
<pathelement location="${build.src}" />
<pathelement location="${build.test}" />
<fileset dir="${lib}">
<include name="**/*.jar"/>
</fileset>
</path>
<target name="run" depends="compile">
<java classname="MyProgram" fork="false">
<classpath refid="classpath"/>
</java>
</target>
Does anyone know why the run task cannot find my classpath?
