Ant needs junit.jar on travis server

When I run ant test everything is cool, but when Travis runs the same command I get
$ ant test

BUILD FAILED
/home/travis/build/AwesomeTeamPlayer/event-receiver/build.xml:42:
Problem: failed to create task or type junit
Cause: the class
org.apache.tools.ant.taskdefs.optional.junit.JUnitTask was not found.
This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in
-/usr/share/ant/lib
-/home/travis/.ant/lib
-a directory added on the command line with the -lib argument
Do not panic, this is a common problem.
The commonest cause is a missing JAR.
This is not a bug; it is a configuration problem
When I changed ant test to ant test -lib ./lib/junit-4.12.jar in .travis.yml file I get the same error message :/

I figure out what to do. I added
before_script:
- sudo apt-get install ant-optional
and that fixed my problem ;)

As mentioned on https://docs.travis-ci.com/user/installing-dependencies/:
To install Ubuntu packages that are not included in the standard
precise, trusty, xenial, or bionic distribution, use apt-get in the
before_install step of your .travis.yml.
Which translates to adding the following to your .travis.yml file:
before_install:
- sudo apt-get install ant-optional

how to supply property file as class path

I am creating webservice using AXIS and running this using ANT script.
<target if="jars.ok" depends="make.repo" name="start.server">
<property name="port" value="7070"/>
<java fork="true" classname="org.apache.axis2.transport.http.SimpleHTTPServer">
<arg value="${build}/repo"/>
<classpath refid="axis2.class.path"/>
<arg value="-p${port}"/>
</java>
</target>
Setted classpath using
<path id="axis2.class.path">
<pathelement path="${java.class.path}"/>
<pathelement path="${maven.class.path}"/>
<fileset dir="${axis2.home}">
<include name="lib/*.jar"/>
<include name="resources/*.properties"/>
</fileset>
</path>
But i am getting error as
[java] log4j:WARN Please initialize the log4j system properly [SimpleHTTPServer]
What do I need to do to fix this issue, thanks a lot

You can not add Property files as classpath, just folders and Jar files.
So here include the whole resources folder:
pathelement path="${axis2.home}/resources"

Eclipse don't recognize test folder as source folder when importing ant build file

I have an ant build file for a java project the project tree looks like this :
DataBaseFidling.
|-->src (contains production code source)
|-->tests (contains tests code source)
|-->bin (contains .class)
|-->reports(contains junit xml reports)
|-->build.xml
Whenever I import this project with eclipse using "Java Project From Existing Ant Build File", eclipse does not reconize the tests folder as a source folder.
What to do to fix this?
Here is the ant build file :
The DatabaseFidling Project.
<property name="src.dir" location="./src/" />
<property name="tests.dir" location="./tests/" />
<property name="bin.dir" location="./bin/" />
<property name="lib.dir" location="/home/chedy/workspace/lib"/>
<target name="clean">
<delete verbose="true">
<fileset dir="${bin.dir}"/>
</delete>
</target>
<target name="compile">
<javac srcdir="${src.dir}" destdir="${bin.dir}">
</javac>
<javac srcdir="${tests.dir}" destdir="${bin.dir}">
<classpath>
<pathelement location="${lib.dir}/junit4.jar"/>
<pathelement location="${lib.dir}/mockito-all-1.9.5.jar"/>
<pathelement location="${lib.dir}/SQLScriptRunner.jar"/>
</classpath>
</javac>
</target>
<target name="test" depends="compile">

<pathelement location="${lib.dir}/SQLScriptRunner.jar"/>
<pathelement location="${lib.dir}/mysql-connector-java-5.1.23-bin.jar" />
</classpath>
<batchtest todir="./report">
<fileset dir="${bin.dir}">
<include name="**/**Test*.*"/>
</fileset>
</batchtest>
</junit>
</target>
<target name="run" depends="compile">
<java classname="com.esprit.is.Main" fork="true">
<classpath>
<pathelement path="${bin.dir}"/>
<pathelement location="${lib.dir}/mysql-connector-java-5.1.23-bin.jar" />
</classpath>
</java>
</target>
</project>

You can manually add the test folder as a source folder. Right click the project, Build Path -> Configure Build Path -> Java Build Path. In the Source tab, click Link Source then browse to your folder.

The compile target had to contain one javac task which compiles both the src and test folders.

Can't run leJOS NXJ sample project

I try to install leJOS NXJ on my MAC OS X and run it's sample, but after I do what it wants and export NXJ_Home Path file and etc. and install netbeans plugin and create it sample project (Creating your own project using the Netbeans Plugin). I also follow this structure and replace desire classes.jar from intsall leJOS NXJ installation's lib folder.
I export these 4 lines:
My-macbook-pro:~ AR$ export NXJ_HOME=/Users/AR/Documents/Research-kar/JAVA/lejos_nxj
My-macbook-pro:~ AR$ export DYLD_LIBRARY_PATH=$NXJ_HOME/bin
My-macbook-pro:~ AR$ export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
My-macbook-pro:~ AR$ export PATH=$PATH:$JAVA_HOME/bin:$NXJ_HOME/binamirrezas-macbook-pro:~ AR$
This is leJOS NXJ sample code:
package org.lejos.example;
import lejos.nxt.*;
/**
* Example leJOS Project with an ant build file

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
Button.waitForPress();
}
}
and this is related build.xml file:

a little bit late but may other like me are looking for a solution. I am new on leJOS and Netbeans and Java (starting tonight).
My environment is WindowsXP with Netbeans 6.9.1.
leJOS is installed in C:/Programme/leJOS NXJ
First Project: HelloWorld
I fixed it by setting the nxj.home var in the build.properties file laying in the project root directory (here /HelloWorld/ and build.xml is also there).
The nxj.home has to point to the leJOS installation path. In my case:
nxj.home=C:/Programme/leJOS NXJ
Hope it helps

java ant buildfile for project with dependencies

I am new to ant, but am trying to create an ant script that builds my current proeject with another project as a dependency. I have the ant script building my current project, but am unsure how to add the other project to the classpath. Neither project get put into jar files at the moment.
My current portion of the build.xml file is
<target name="run" depends="compile">
<java classname="com.mypackage.Main">
<classpath>
<pathelement location="../project1/out"/>
<pathelement location="${bin}"/>
</classpath>
</java>
</target>
Thanks for your help!

I was able to do it using
<target name="run" depends="compile">
<java classname="com.mypackage.Main" fork="true">
<classpath>
<dirset dir="${other.dir}">
<include name="out/**"/>
</dirset>
<pathelement location="${bin}" />
</classpath>
</java>
</target>
Where ${other.dir} is the relative path to the root of the other project.
