ant java jar classpath problem - ant

<target name="results">
<echo message="Calculating QI" />
<java jar="jmt.jar" fork="true" failonerror="true" maxmemory="1024m" classpath="jmt/jmt">
<arg value="-name:KIS"/>
<arg value="-results:CONSOLE"/>
<arg value="../allJavas.jar"/>
</java>
</target>
i want from folder tmp run jar file in folder jmt/jmt. It must be run inside jmt/jmt folder becouse of dependencies files.
i can run it like <java jar="jmt/jmt/jmt.jar" but then dependencies files are not ok. I try to use classpath but not working. What i am doing wrong?

Use the dir="jmt/jmt" attribute to specify the folder to launch the java process in, and use jar="jmt/jmt/jmt.jar" to specify the jar. You probably don't need to classpath attribute at all.
See http://ant.apache.org/manual/Tasks/java.html

The java ant task takes an option parameter dir="jmt/jmt" that will tell the forked VM where to execute.

How to specify lib directory for ant task?

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"/>

JSCover - Excluding coverage files

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

running specific target in different ant scripts in different directories

We have a large amount of apps. They all have a build.xml file located in the projects base directory. I am trying to create an ant script that will go through and call a specific target on each of the build.xml files in all the projects.
Here are the issues:
Some of the projects are in deeper directories than others.
Only some of the projects need to be built at a time.
I was trying to use subant + antfile and defining a CSV of file paths in a properties file, but this did not work. Below is what i have and the error i am getting.
If there is a better way to do this or you know what my problem is, please let me know! Thanks!
This is the property defined in a property file. I am wanting the person running the script to add the file paths in here that are relative to the current location of the script they are running.
projects.to.build=
This is the subant task i am trying to use in the main build script.
<filelist
id="projectNames"
dir="${basedir}"
files="${projects.to.build}"
/>
<target name="debugAll" description="Builds all the projects listed in the projectNames.properties file.">
<subant target="debug" antfile="${projects.to.build}">
</subant>
</target>
Here is the error i get when i try to run the build script when there are projects defined in the properties file. I am using the relative path. For example: ..\Apps\AnApp1\build.xml,..\Apps\AnApp2\build.xml,..\OtherApps\foo\AnotherApp1\build.xml
"No Build Path Specified" (at my subant task)
You specified the antfile attribute, so ANT was expecting to a single build.xml file.
The subant documentation describes how you can use a fileset as child parameter.
Here's an example:
<project name="Subant demo" default="run-debug-target">
<target name="run-debug-target">
<subant target="debug">
<fileset dir="." includes="**/build.xml" excludes="build.xml"/>
</subant>
</target>
</project>
Update
Alternatively a filelist could be used:
<project name="Dry run" default="run">
<target name="run">
<subant target="test">
<filelist dir="projects" files="one/build.xml,two/build.xml,three/build.xml,four/build.xml"/>
</subant>
</target>
</project>
Processing the following build files:
projects/one/build.xml
projects/two/build.xml
projects/three/build.xml
projects/four/build.xml
Is it possible to run the target in the all the build files concurrently ?
E.g.
<project name="Dry run" default="run">
<target name="run">
<subant target="test">
<filelist dir="projects" files="one/build.xml,two/build.xml,three/build.xml,four/build.xml"/>
</subant>
</target>
</project>
In this example, is there any way to run target "test" present in all the build files (one/build.xml,two/build.xml,three/build.xml,four/build.xml) concurrently ?

Is there a way to call the ant 'ant' target with '-lib' option

I'm developing an ant script which is calling another ant script using the <ant> task. This ant script is an installer a Java product and is to be used by our customers, who will have ant installed separately.
The script being called uses the antlr task <antlr:ant-antlr3>. To do this I must place the ant-antlr3.jar file in the ant lib directory, as well as adding antlr-3.2.jar to the classpath.
But I don't want to have this dependency of having ant-antl3.jar file in the client's own installed version of ant.
Is there a way of providing the equivalent to ant's command-line '-lib' option to specify other paths for jars to be added to antlib using the <ant> task itself?
I've taken a look at the online docs and there doesn't seem to be a way.
Thanks
I believe the accepted way to do this is to manually set up your classpath in the build file rather than implicitly including it via the global ant lib directory. i.e.
<path id="master-classpath">
<fileset dir="${lib}" />
<fileset file="${findbugs-base}/lib/annotations.jar" />
<pathelement location="${build-classes}" />
</path>
You can then use this path element in any task that can accept classpath args such as javac
<javac
destdir="${out}"
source="1.5"
target="1.5"
debug="true">
<src path="${src}" />
<classpath refid="master-classpath" />
</javac>
This way, the global ant set up isn't a dependency, and you can specify any files you might need for any build, as specifically as you need to (down to a given call or target).
Obviously, this is all to be carried out in the build file you're calling from the clients' build file. This way, when you call out to yours, the classpath will be set up exactly as you desire.
Another far less idiomatic possibility would be to literally shell out with the Exec Task and call ant that way. Obviously, with the provision of the Ant task, the developers of ant don't recommend you doing that. It is an option, nonetheless.
Tim's answer gives most of the story, but in order to run Ant and set JVM options, you'd need to invoke it via the java task.
There is an example of running this way in the Ant docs, here slightly modified to include -lib:
<java
classname="org.apache.tools.ant.launch.Launcher"
fork="true"
failonerror="true"
dir="${sub.builddir}"
timeout="4000000"
taskname="startAnt"
>
<classpath>
<pathelement location="${ant.home}/lib/ant-launcher.jar"/>
</classpath>
<arg value="-lib"/>
<arg value="${path.to.your.antlr.jar}"/>
<arg value="-buildfile"/>
<arg file="${sub.buildfile}"/>
<arg value="${sub.target}"/>
</java>

How to execute the JAXB compiler from ANT

I am using JAXB on a project. the attraction of JAXB is that it is bundled with the JDK, I have been to use xjc.exe on the command line to generate the .java files from a schema. I can't seem to find the JAXB ant task, sure there is a download at http://jaxb.java.net however i want to use the JAXB that is bundled into the JDK is there some way to call JAXB from ant what class does the xjc.exe call on?
<target name="generate-jaxb-code">
<java classname="com.sun.tools.internal.xjc.XJCFacade">
<arg value="-p" />
<arg value="com.example"/>
<arg value="xsd/sample.xsd" />
</java>
</target>
Just went hunting in the tools.jar and found the XJCFacade.class in com.sun.tools.internal tested the above code it works it produces the output as xjc.exe It seems that XJC.exe calls this code com.sun.tools.internal.xjc.XJCFacade
One of my key requirements was that the ant file had work within eclipse without having to include a path name to the JDK that way the file would be portable across operating systems. I am assuming that tools.jar is included on the classpath via the installed JRE preferences options.
Here is a helpful link:
https://jaxb.java.net/nonav/2.0.2/docs/xjcTask.html
Java SE 6 does not ship the Ant task (see 7.1.3):
https://jaxb.java.net/guide/Migrating_JAXB_2_0_applications_to_JavaSE_6.html
Essentially they do the following:
<target name="xjc" description="....">
<exec executable="${jdk.dir}/bin/xjc.exe">
<arg value="-d"/>
<arg value="${src.dir}"/>
<arg value="-p"/>
<arg value="com.mydomain.jaxb"/>
<arg value="${etc.dir}/myschema.xsd"/>
</exec>
</target>
