java - Travis CI can't find Ivy jarfile -

i'm new java , travis ci, , running error configuring project. i'm using ant build, , ivy manage dependencies. ant build downloads ivy jarfile directly if it's not found locally. works fine on machine, fails when push travis.

the puzzling thing: looks downloads jar , puts in /home/travis/.ant/lib/ during bootstrap-ivy task, fails find in resolve task follows. idea what's going on? full error, ant buildfile, , .travis.yml included below.

here's full travis error:

and here's .travis.yml:

language: java install: ant resolve jdk:   - oraclejdk7   - openjdk7   - openjdk6 

update: here's solution worked me, advice below.

i replaced custom bootstrap-ivy task download-ivy , init-ivy tasks recommended in official docs:

    <property name="ivy.install.version" value="2.1.0-rc2" />     <condition property="ivy.home" value="${env.ivy_home}">       <isset property="env.ivy_home" />     </condition>     <property name="ivy.home" value="${user.home}/.ant" />     <property name="ivy.jar.dir" value="${ivy.home}/lib" />     <property name="ivy.jar.file" value="${ivy.jar.dir}/ivy.jar" />      <target name="download-ivy" unless="offline">          <mkdir dir="${ivy.jar.dir}"/>         <!-- download ivy web site can used without special installation -->         <get src="http://repo2.maven.org/maven2/org/apache/ivy/ivy/${ivy.install.version}/ivy-${ivy.install.version}.jar"               dest="${ivy.jar.file}" usetimestamp="true"/>     </target>      <target name="init-ivy" depends="download-ivy">       <!-- try load ivy here ivy home, in case user has not dropped               ant's lib dir (note latter copy take precedence).               not fail long local lib dir exists (it may empty) ,               ivy in @ least 1 of ant's lib dir or local lib dir. -->         <path id="ivy.lib.path">             <fileset dir="${ivy.jar.dir}" includes="*.jar"/>          </path>         <taskdef resource="org/apache/ivy/ant/antlib.xml"                  uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/>     </target> 

i added before_install step .travis.yml, runs ant init-ivy before trying resolve dependencies (here docs on travis build cycle):

language: java before_install: ant init-ivy install: ant resolve jdk:   - oraclejdk7   - openjdk7   - openjdk6 

now everything's working!

this related way ant loading jars .ant/lib. folder being looked @ boot of ant, , if jar found there added core classloader. here .ant/lib being populated while executing build, way late.

two choices resolve this:

• launch ant twice; 1 populate .ant/lib, actual build
• instead of putting jar of ivy in .ant/lib, put in arbitrary place , load via taskdef ant task. see 'automatically' section of http://ant.apache.org/ivy/history/latest-milestone/install.html
