Ant build fails saying: package doesn't exist - ant

I get the followingn errors saying

log4j-1.2.16.jar is present in classpath.
I get similar errors for other jars too

Jacoco coverage with Ant throws java.lang.instrument.IllegalClassFormatException: Error while instrumenting class

I integrated Jacoco with my Ant build. When I run the build, the test case is executed successfully followed by the below exception in my TEST-com.worker.ManagerTest.xml.
When I add excludes="*" the error is not thrown. But the jacoco.exec is generated with 1kb size and when I run the report nothing is generated. Can someone let me know what am I missing?
Exception:
<![CDATA[java.lang.instrument.IllegalClassFormatException: Error while instrumenting class com/dataaccess/GenericDao.

Below is the jacoco build script.

This is the empty report I get.

I used the latest version 0.8.7 and it worked.

Ant - Generate .class files even if compiler errors

How to successfully build using Ant, if the code has compilation errors?
If I have 3 .java files and 1 has a compilation error, is there anything that can make my build successful and can give me the remaining 2 .class files?
<target name="build" description="Compiles the Source code" depends="Directory.check">
<echo>Compilation Starts</echo>
<javac failonerror="false" includeantruntime="false" destdir="${build.dir}"
deprecation="false" optimize="true" executable="${exec.dir}">
<compilerarg value="-Xlint:unchecked"/>
<compilerarg value="-Xlint:deprecation"/>
<src path="${src.dir}"/>
<classpath refid="master-classpath"/>
</javac>
<echo>Compilation Ends</echo>
</target>
Iterate though src files using for from ant-contrib.
Pass the file name to javac in includes attribute with the src basedir as srcdir.
<target name="compile" depends="init" description="compile the source ">
<for param="file">
<path>
<fileset dir="${src}" includes="**/*.java" excludes="**/Sanity/*.java"/>
</path>
<sequential>
<local name="program"/>
<basename property="program" file="#{file}" suffix=".java"/>
<javac includeantruntime="false" srcdir="${src}" debug="on" includes="**/${program}.java"
excludes="**/Sanity/*.java" destdir="${build}" failonerror="false"
verbose="true">
<compilerarg value="-Xbootclasspath/p:${toString:lib.path.ref} -Xlint:deprecation -Xlint:unchecked"/>
</javac>
</sequential>

How to run dbunit task in ant?

It doesn't work in ant,
I'd like to run some classes that extend DatabaseTestCase
<path id="libs.dir">
<fileset dir="lib" includes="**/*.jar" />
</path>
<taskdef name="dbunit"
classname="org.dbunit.ant.DbUnitTask"/>
<!-- run all tests in the source tree -->
<junit printsummary="yes" haltonfailure="yes">
<formatter type="xml"/>
<batchtest fork="yes" todir="${reports.tests}">
<fileset dir="${src.tests}">
<include name="**/*Test*.java"/>
</fileset>
</batchtest>
</junit>
It says the following:
Buildfile: D:\kariakin\jdbc_task\build.xml
BUILD FAILED
D:\kariakin\jdbc_task\build.xml:15: taskdef class org.dbunit.ant.DbUnitTask cannot be found
using the classloader AntClassLoader[]
I think the problem is your taskdef, it's missing the path containing the dbunit jar:
<taskdef name="dbunit" classname="org.dbunit.ant.DbUnitTask" classpathref="libs.dir"/>

Execute a jar file using Ant

I am trying to create a runnable jar file from java classes using ant. The java classes use external jars. When I execute the build.xml its showing class not found exception while running the java program. Its compiling fine.
Part of My source code:
<path id="project-libpath">
<fileset dir="${lib.dir}">
<include name="*.jar"/>
</fileset>
</path>
<path id="project-classpath">
<fileset dir="C:/xmldecode/lib">
<include name="*.jar"/>
</fileset>
</path>
<target name="compile" depends="prepare">
<javac srcdir="${src.dir}" destdir="${classes.dir}">
<classpath refid="project-classpath"/>
</javac>
</target>
<target name="jar" depends="compile">
<copy todir="${classes.dir}">
<fileset dir="C:/xmldecode/lib"/>
</copy>
<pathconvert property="mf.classpath" pathsep=";">
<path refid="project-classpath" />
<flattenmapper />
</pathconvert>
<jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
<manifest>
<attribute name="Main-Class" value="${main-class}"/>
<attribute name="Class-Path" value="${mf.classpath}"/>
</manifest>
</jar>
</target>
<target name="run" depends="jar">
<java jar="${jar.dir}/${ant.project.name}.jar" fork="true">
</java>
Your problem is that the manifest classpath entries are not separated by a ";" character.
The following will work better I think:
<pathconvert property="mf.classpath" pathsep=" ">
<path refid="project-classpath" />
<flattenmapper />
</pathconvert>
Could I suggest using the new ANT task manifestclasspath ?
<manifestclasspath property="mf.classpath" jarfile="${jar.dir}/${ant.project.name}.jar">
<classpath refid="project-classpath" />
</manifestclasspath>
This powerful method will determine paths relative to the jar's location, for example if the jar's dependencies are located in a lib directory

Ant for EJB project

I am trying to make an ant script for an EJB project. I am using Jboss for this.
I am new to both EJB and Ant and am having problems in getting the beans to compile from ant. It gives me number of errors of the kind
package javax.persistence does not exist
#MappedSuperclass - Cannot find symbol
I created it as an eclipse project initially, and added the jboss runtime through eclipse. Do I need to copy all the jars in a lib folder and include them in the classpath for the beans to compile or is there a better way to do this?
Try setting classpath in Ant appropriately. It ignores any system CLASSPATH or Eclipse setting that you have.
Here's an Ant build.xml that you can start with:
