java - Using ant and build.xml error -


when try run program on gl server, error. also, have 2 packages, 1 is, , other driver package has driver.java in it. runs program.

build failed target "run" not exist in project "autofill".

why this? here build.xml

<?xml version="1.0" encoding="utf-8" standalone="no"?> <!-- warning: eclipse auto-generated file.           modifications overwritten.           include user specific buildfile here, create 1 in same           directory processing instruction <?eclipse.ant.import?>           first entry , export buildfile again. --> <project basedir="." default="build" name="autofill"> <property environment="env"/> <property name="debuglevel" value="source,lines,vars"/> <property name="target" value="1.7"/> <property name="source" value="1.7"/> <path id="autofill.classpath">     <pathelement location="bin"/> </path> <target name="init">     <mkdir dir="bin"/>     <copy includeemptydirs="false" todir="bin">         <fileset dir="src">             <exclude name="**/*.launch"/>             <exclude name="**/*.java"/>         </fileset>     </copy> </target> <target name="clean">     <delete dir="bin"/> </target> <target depends="clean" name="cleanall"/> <target depends="build-subprojects,build-project" name="build"/> <target name="build-subprojects"/> <target depends="init" name="build-project">     <echo message="${ant.project.name}: ${ant.file}"/>     <javac debug="true" debuglevel="${debuglevel}" destdir="bin" includeantruntime="false" source="${source}" target="${target}">            <src path="src"/>         <classpath refid="autofill.classpath"/>     </javac> </target> <target description="build projects reference project. useful  includeantruntime="false" source="${source}" target="${target}"> <target description="copy eclipse compiler jars ant lib directory" name="init-     <copy todir="${ant.library.dir}">         <fileset dir="${eclipse_home}/plugins" includes="org.eclipse.jdt.core_*.jar"/>     </copy>     <unzip dest="${ant.library.dir}">         <patternset includes="jdtcompileradapter.jar"/>         <fileset dir="${eclipse_home}/plugins" includes="org.eclipse.jdt.core_*.jar"/>     </unzip> </target> <target description="compile project eclipse compiler" name="build-eclipse   compiler">     <property name="build.compiler" value="org.eclipse.jdt.core.jdtcompileradapter"/>     <antcall target="build"/> </target> <target name="maxheap">     <java classname="proj3.maxheap" failonerror="true" fork="yes">         <classpath refid="autofill.classpath"/>     </java> </target> <target name="driver">     <java classname="driver.driver" failonerror="true" fork="yes">         <classpath refid="autofill.classpath"/>     </java> </target> </project>

i've reformatted build.xml here. there issues it:

i don't know if miscopied it, it's not valid ant build file stands now. may want check post , see if missed anything.

your error pretty straight forward. don't have target named run. have no idea why executing it. (maybe it's in section of build.xml messed up.

the valid targets are:

  • init
  • clean
  • cleanall
  • build
  • build-project
  • build-subprojects
  • init-??? (target name not complete)
  • build-eclipse compiler (invalid target name. can't contain space)
  • maxheap (java executable)
  • driver (java executable)

if you're attempting compile project, want run build-project or build target , not run. (both build-project , build same thing).

if you're attempting run program, maxheap , driver 2 java executable targets in build.xml.

so, want execute targets build , driver or maxheap.
