I am trying to run findbugs through ant. This is a snippet of a part of my build file:
<taskdef name="findbugs" classname="edu.umd.cs.findbugs.anttask.FindBugsTask" >
<classpath>
<fileset dir="${findbugs.home}/lib" includes="**/*.jar"/>
<pathelement location="${project.target.android.jar}" />
</classpath>
</taskdef>
<path id="build.classpath">
<pathelement location="${project.target.android.jar}" />
<fileset dir="libs">
<include name="*.jar"/>
</fileset>
</path>
<target name="findbugs" >
<findbugs home="${findbugs.home}" output="html" outputFile="findbugs/findbugs.html">
<class location="${out.classes.absolute.dir}" />
<auxClasspath refId="build.classpath"/>
<sourcePath path="${source.absolute.dir}" />
</findbugs>
</target>
This is unable to recognize the android library and gives errors like: cannot find android.os.Bundle,
etc,...
How do I make it recognize android libraries? I have tried including it using , but this doesn't seem to work.
I am not aware of the complete build file, but the main project compilation works fine, and the android lib included there are in this format:
<gettarget
androidJarFileOut="project.target.android.jar"
...
Findbugs works on Java's class file format. Android uses another format called dex. So Findbugs will not work on that.

I writing an ant build file to check all translate files in a directory.
I want the ant for script to continue checking the rest files if an checking error in any file appear.
My ant task:
<taskdef name="validate" classname="ValidateTranslateFile">
<classpath>
<pathelement location="${ant-libs-dir}/TranslateFileUtilities.jar" />
<pathelement location="../web/WEB-INF/lib/commons-io-2.5.jar" />
<pathelement location="../web/WEB-INF/lib/commons-lang3-3.5.jar" />
</classpath>
</taskdef>
<for param="program">
<path>
<fileset dir="../web/WEB-INF" includes="*.txt" />
</path>
<sequential>
<validate targetFile="#{program}" checkLanguages="true" checkKeysOrder="true" />
</sequential>
</for>
</target>
the Result:
it checks the files till the first error appear, and then the BUILD FAILED.
Could any one help me with that?
The for task is not part of standard ANT. It is a 3rd party extension documented here:
http://ant-contrib.sourceforge.net/tasks/tasks/for.html
The documentation suggests using a "keepgoing" attribute to ignore errors, this might be the answer you're looking for.
If this is a custom ANT task you are writing, perhaps you should consider refactoring the code to operate on a fileset? This would enable you to call task as follows:
<validate checkLanguages="true" checkKeysOrder="true">
<fileset dir="../web/WEB-INF" includes="*.txt" />
</validate>
Simpler and more robust.
The following is a simplified version of my ant script (it's got the project element etc).
I'm new to ant and unable to figure out why 'compileTests' doesn't compile, whereas 'compileFoo' does.
The error I get is 'package does not exist' as the class in the compileTests project can't find the compiled classes in the compileFoo project, even though they've compiled fine, i can see them on the file system and the path to them is listed in the classpath (i assume this is necessary?)
Clearly there is something basic I don't understand. Can someone please help by explaining?
<path id="build_classpath">
<fileset dir="${other_required_jars}" includes="**/*.jar" />
<fileset dir="${foo_build_location}" includes="**/*.class" />
</path>
<target name="compileFoo" description="compile">
<javac srcdir="${foo_source_directory}\test-src" includeantruntime="false" destdir="${foo_build_location}" includes="**/*.java" excludes="" debug="on" optimize="off" deprecation="on" verbose="on">
<classpath refid="build_classpath" />
</javac>
</target>
<target name="compileTests" description="compile">
<javac srcdir="${test_source_directory}\test-src" includeantruntime="false" destdir="${test_build_location}" includes="**/*.java" excludes="" debug="on" optimize="off" deprecation="on" verbose="on">
<classpath refid="build_classpath" />
</javac>
</target>
Your classpath is wrong. A classpath doesn't contain a set of .class files. It cntains a set of jar or directories, each containing the root of a package tree. So the classpath should simply contain one element : ${foo_build_location}:
<path id="build_classpath">
<fileset dir="${other_required_jars}" includes="**/*.jar" />
<pathelement location="${foo_build_location}"/>
</path>
I have the following ANT script that gives me a list of websphere libraries at runtime based on the websphere root directory. I need to convert the resulting string into separate path location elements
My current script is
<?xml version="1.0" encoding="UTF-8"?>
<project name="TestPath" basedir="." default="print-dirset">
<target name="init" description="Define websphere libraries">
<property name="compile.lib.dir" value="C:\Software\WAS85" />
</target>
<target name="print-dirset" depends="init" description="">
<path id="websphere.libs">
<dirset dir="${compile.lib.dir}">
<include name="*" />
</dirset>
</path>
<property name="websphere.libs.list" refid="websphere.libs" />
<echo message="websphere.libs.list: ${websphere.libs.list}" />
<pathconvert property="websphere.libs.convert" pathsep="${file.separator}*${path.separator}">
<path path="${websphere.libs.list}" />
</pathconvert>
<echo message="websphere.libs.convert: ${websphere.libs.convert}" />
</target>
</project>
which outputs a string like below
[echo] websphere.libs.list: C:\Software\WAS85\Scheduler;C:\Software\WAS85\UDDIReg;C:\Software\WAS85\bin;C:\Software\WAS85\configuration;....C:\Software\WAS85\web;C:\Software\WAS85\wlp
[echo] websphere.libs.convert: C:\Software\WAS85\Scheduler\*;C:\Software\WAS85\UDDIReg\*;C:\Software\WAS85\bin\*;C:\Software\WAS85\configuration\*;...C:\Software\WAS85\web\*;C:\Software\WAS85\wlp
I would like to translate the second string above into a structure like below
<path id="websphere.classpath">
<pathelement location="C:\Software\WAS85\Scheduler\*" />
<pathelement location="C:\Software\WAS85\UDDIReg\*" />
<pathelement location="C:\Software\WAS85\bin\*" />
<pathelement location="C:\Software\WAS85\configuration\*" />
......
<pathelement location="C:\Software\WAS85\web\*" />
<pathelement location="C:\Software\WAS85\wlp\*" />
</path>
The last element in the conversion also needs to add the '\*' part which is not in the original string.
which can then be used with a structure like
<path id="compile.classpath">
<path refid="ext.classpath"/>
<path refid="websphere.classpath"/>
<path refid="module.compile.classpath"/>
</path>
The purpose of the above attempt is to reduce the length of classpath by using wildcard classpath provided by JDK 1.6 and which is available in ANT starting ANT 1.8.2. I am using ANT 1.8.4.
I am not an expert in ANT, I can just get by, by looking at examples.
Is there a way to achieve what I am trying to do? How can I do it? Any example would be very helpful.
If all of your dependencies reside in C:\Software\WAS85, you can use fileset to catch all of your dependencies:
<fileset dir="${compile.lib.dir}" id="compile.files">
<include name="**/*.java"/>
<!-- include name="**/*.jar" /-->
</fileset>
You can then use to refer to this fileset as compile.files elsewhere in your build.xml.
I was able to get the wildcard part to work by using the fork="yes" and executable="path-to-my-executable" attributes in the javac task.
I do not want to mark the question answered, because my basic question was about converting the string. But since the answer received didn't talk about that and also didn't mention how to get wildcard classpath working, and the purpose of my question was to get the wildcard classpath working, i have noted it here for whoever is trying to get that to work
I still need some help in converting the semi-colon separated string to construct like below
<path id="websphere.classpath">
<pathelement location="C:\Software\WAS85\Scheduler\*" />
<pathelement location="C:\Software\WAS85\UDDIReg\*" />
<pathelement location="C:\Software\WAS85\bin\*" />
<pathelement location="C:\Software\WAS85\configuration\*" />
......
<pathelement location="C:\Software\WAS85\web\*" />
<pathelement location="C:\Software\WAS85\wlp\*" />
</path>
Update:
I wrote a custom ANT task to get the wildcard classpath working
I am trying to integrate yuicompressor with Ant to automate the minification of our CSS and JS files. However, I keep getting the following error message when I try to run build.xml:
BUILD FAILED
/Applications/MAMP/htdocs/zanadu-dev/build/build.xml:64: taskdef A class needed by class com.yahoo.platform.yui.compressor.YUICompressTask cannot be found: org/mozilla/javascript/EvaluatorException

Here is the code in my build.xml file:
<target name="minify" depends="build" description="Minifiy CSS and JS files">
<available file="${antlib.dir}/YUIAnt.jar" property="YUIANT_AVAILABLE" />
<fail unless="YUIANT_AVAILABLE" message="YUIAnt.jar not found" />

outputfolder="${cssmin.dir}">
<fileset dir="${css.dir}" >
<include name="**/*.css" />
</fileset>
</yuicompress>
</target>
I have tried following several online examples on this, but all seem to yield the same error message. Not sure exactly where I can find the EvaluatorException class that seems to be missing.
Any idea what I may be doing wrong?
Cheers!
Your taskdef is missing one lib.
<taskdef name="yuicompress" classname="com.yahoo.platform.yui.compressor.YUICompressTask">
<classpath>
<pathelement path="${antlib.dir}/YUIAnt.jar" />
<pathelement path="${antlib.dir}/yuicompressor-2.4.6.jar" />
<pathelement path="${antlib.dir}/rhino-1.6R7.jar" />
</classpath>
</taskdef>
EDIT:,
The problem is somehow related to the jar locations and Ant's class-loader, see this post
One workaround is to copy YUIAnt.jar, yuicompressor-2.4.6.jar and rhino-1.6R7.jar to one directory. Then use it like above. I've tried and it works.
if you use http://code.google.com/p/yui-compressor-ant-task/ for me solution was to use classname="net.noha.tools.ant.yuicompressor.tasks.YuiCompressorTask" instead of classname="com.yahoo.platform.yui.compressor.YUICompressTask"
When declaring external ant tasks using taskdef, for instance ant-contrib, the proposed setup is to use the followin taskdef:
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="lib/ant-contrib/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
This works when antcontrib.properties is located in net/sf/antcontrib relative to the build.xml file.
But when I put it in lib/net/sf/antcontrib and changes the taskdef into
<taskdef resource="lib/net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="lib/ant-contrib/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
Ant is not able to find the properties file, it gives the error
[taskdef] Could not load definitions from resource
lib/net/sf/antcontrib/antcontrib.properties. It could not be found.
It seems like ant treats the lib directory separately and fails to load a taskdef resource from there.
As Alex said, you shouldn't need to unzip the jar. The <taskdef> can load antcontrib.properties directly out of the jar.
The error you got is because you changed the resource path, but the path to the file inside the compressed jar/zip is still the same. The taskdef isn't paying attention to the properties file you moved because the <classpath> you provided to <taskdef> tells it to only look in the jar.
Use antlib.xml resource:
Here is the taskdef definition that I use:
<property name="ant-contrib.jar" location="..."/>
<taskdef
resource="net/sf/antcontrib/antlib.xml"
uri="http://ant-contrib.sourceforge.net"
>
<classpath>
<pathelement location="${ant-contrib.jar}"/>
</classpath>
</taskdef>
You do not need to extract anything from the jar file. Also, uri attribute is optional if you do not want to use namespaces with antcontrib tasks.
To handle classpath for tasks definitions, I use a classpath ref in Ant, it's way easier. You can link either a directory containing classes, either a directory containing many .jar, either (of course) a single .jar.
For example :
<!-- Properties -->
<property name="lib" value="lib/" />
<property name="classes" value="bin/" />
<!-- Classpath definition -->
<path id="runtime-classpath" >
<pathelement location="${bin}" />
<fileset dir="${lib}">
<include name="*.jar"/>
</fileset>
</path>
<!-- Taskdefs definitions -->
<taskdef name="myTask" classname="org.stackoverflow.tasks.MyTask" classpathref="runtime-classpath" />
<!-- Tasks -->
<target name="test" description="Test Action">
<myTask parameter1="value" />
</target>
