java - Travis CI が Ivy jarfile を見つけられない

Question

Java と Travis CI は初めてで、プロジェクトの構成中にエラーが発生しました。ビルドには ant を使用し、依存関係の管理には ivy を使用しています。私の ant ビルドは、ローカルに見つからない場合、ivy jarfile を直接ダウンロードします。これは私のマシンでは問題なく動作しますが、Travis にプッシュすると失敗します。

/home/travis/.ant/lib/不可解なこと: タスク中にjar をダウンロードして配置するように見えますbootstrap-ivyが、その後のタスクでそれを見つけることができませんresolve。何が起こっているのか分かりますか？完全なエラー、私の ant ビルドファイル、および私の.travis.ymlすべてが以下に含まれています。

完全な Travis エラーは次のとおりです。

そして、これが私のもの.travis.ymlです：

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

更新：以下のアドバイスのおかげで、これが私のために働いた解決策です。

カスタムbootstrap-ivyタスクを、公式ドキュメントで推奨されているdownload-ivyおよびタスクに置き換えました。init-ivy

    <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="${ivy.jar.dir}"/>
        <!-- download Ivy from web site so that it can be used even without any special installation -->
        <get src="http://repo2.maven.org/maven2/org/apache/ivy/ivy/${ivy.install.version}/ivy-${ivy.install.version}.jar" 
             dest="${ivy.jar.file}" usetimestamp="true"/>
    </target>

    <target name="init-ivy" depends="download-ivy">
      <!-- try to load ivy here from ivy home, in case the user has not already dropped
              it into ant's lib dir (note that the latter copy will always take precedence).
              We will not fail as long as local lib dir exists (it may be empty) and
              ivy is in at least one of ant's lib dir or the 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>

依存関係を解決しようとする前に実行されるbefore_installステップをに追加しました(ここに Travis ビルド サイクルに関するドキュメントがあります)。.travis.ymlant init-ivy

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

今、すべてが機能しています！
