我正在尝试使用jarbundler创建带有ant的.app文件。但是我收到以下错误:
找不到taskdef类net.sourceforge.jarbundler.JarBundler
使用类加载器
AntClassLoader [/Users/Ida/NetBeansProjects/supernova/build/classes/lib/jarbundler-core-3.3.0.jar]
我的build.xml看起来像这样:
<path id="classpath">
<fileset dir="dist/lib">
<include name="*.jar"/>
</fileset>
</path>
<target name="clean">
<delete dir="build"/>
</target>
<target name="compile">
<mkdir dir="build/classes"/>
<javac srcdir="src" destdir="build/classes">
<classpath>
<path refid="classpath"/>
<path location="${jar.dir}/${ant.project.name}.jar"/>
</classpath>
</javac>
<copy todir="build/classes">
<fileset dir="src" excludes="**/*.java"/>
</copy>
</target>
<target name="dist">

</target>
<target name="run" depends="jar">

<classpath>
<path refid="classpath"/>

</java>
</target>
<target name='package-app'>
<taskdef name="jarbundler" classname="net.sourceforge.jarbundler.JarBundler">
<classpath>
<pathelement location="build/classes/lib/jarbundler-core-3.3.0.jar"/>
</classpath>
</taskdef>
<jarbundler dir="dist" name="SuperNova"
mainclass="com.lumenradio.supernova.SuperNovaApp"
jar="build/jar/SuperNova.jar"/>
</target>
是否有人现在为什么会出现此错误以及如何解决?
编辑
谢谢你的帮助。我现在可以构建.app文件,但是当我尝试运行它时,出现以下错误:
错误:找不到或加载主类
com.lumenradio.supernova.SuperNovaApp
我的目标现在看起来像这样:
<target name='package-app'>
<taskdef name="jarbundler" classpath="build/classes/lib/jarbundler-core-3.3.0.jar"
classname="com.ultramixer.jarbundler.JarBundler"/>
<jarbundler dir="dist" name="SuperNova"
jar="build/jar/SuperNova.jar"
mainclass="com.lumenradio.supernova.SuperNovaApp"
icon="SuperNova copy.icns"
stubfile="universalJavaApplicationStub"
useJavaXKey="true"
jvmversion="1.7+"/>
</target>
最佳答案
我下载了jar进行查看,我认为问题是您的classname
错误。 JarBundler类位于com.ultramixer.jarbundler.JarBundler
中,因此请尝试以下操作:
<taskdef name="jarbundler" classname="com.ultramixer.jarbundler.JarBundler">
<classpath>
<pathelement location="build/classes/lib/jarbundler-core-3.3.0.jar"/>
</classpath>
</taskdef>
另外,由于仅加载单个库,因此不需要使用嵌套的类路径来代替
taskdef
的classpath
属性,因此可以对其进行一些简化: <taskdef
name="jarbundler"
classname="com.ultramixer.jarbundler.JarBundler"
classpath="build/classes/lib/jarbundler-core-3.3.0.jar"
/>
关于java - 将Jarbundler与 Ant 配合使用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/45081471/
