When I build with ant my project that uses libgdx, I get a strange error. It says that a class com.google.gwt.dom.client.ImageElement is not found, but it isn't used at all in the code. How can I find what makes this class necessary? Even searching over the whole project doesn't give any results. It says that error is at PixmapTextureAtlas.java:16 (class source), but there is no code that uses that ImageElement class. Adding the library containing com.google.gwt.dom.client.ImageElement class helps, of course, but I'd like to figure out why this class in needed.
Here is the place in ant log that tells of the actual error:

A given library may have dependencies that it does not provide, so your code needs it indirectly. PixmapTextureAtlas.java:16 does reference this class, and you use PixmapTextureAtlas, therefore you indirectly need com.google.gwt.dom.client.ImageElement.
A tool like Maven can add dependencies/subdependencies and manage them easily.
I found out why that was happening. I accidentally added to classpath two different jars where are two different variants of class com.badlogic.gdx.graphics.Pixmap, one having dependency on GWT, and another being the one I needed. The problem was that I didn't know such situation is possible : )
Here's the error I keep getting at runtime:
[java] Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException
Note, this is a runtime error, not a compile-time one. Both tasks in my build.xml have an identical classpath set, and the compile task runs fine every single time:
<path id="classpath">
<fileset dir="lib" includes="*.jar" />
</path>
<target name="compile">
<mkdir dir="build/classes"/>
<javac
srcdir="src"
classpathref="classpath"
includeantruntime="false"
destdir="build/classes"
/>
</target>
...
<target name="run" depends="clean,compile,jar">
<java
jar="build/jar/${project.name}.jar"
fork="true"
classpathref="classpath"
>
<sysproperty key="java.library.path" path="${path.lib}/windows"/>
</java>
</target>
Trying to run the jar via command-line manually yields the same result:
java -cp .:lib/*.jar -Djava.library.path=lib/windows -jar build/jar/JUtopia.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException
Note that the library jarfile is ok:
bash-3.1$ jar -tf lib/lwjgl.jar | grep LWJGLException
org/lwjgl/LWJGLException.class
And the native libraries are in place:
bash-3.1$ ls lib/windows/lwjgl.dll
lib/windows/lwjgl.dll
The question: where the blazes have I gone wrong? I've been beating at this problem for nearly 3 days. Any help would be much appreciated.

P.S.: Note, I'm using Console2 with bash in a windows environment for my commandline work, thus the windows natives yet linux shell syntax. Using vanilla cmd to run the jar yields the same result.
-jar...
When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored. - reference
try setting the Class-Path in the JAR
Alternatively try running without the -Jar option, by specifying the main class on the command line
One of the possible causes is that while loading the class LWJGLException it also references another class which can't be found on the classpath. Hence the reported error is sometimes not clear.
Important here is thet you have this NoClassDefFoundError and not ClassNotFoundException which is the error you assume you are having: it cannot find the class LWHLException, yes it can ! But it cannot load it....
I am trying to build using an Ant task that uses exec. Here is a snippet of my task:
<exec executable="cmd" failonerror="true" osfamily="windows">
<arg value="/c" />
<arg value="${path.installer}" />
<arg value="-silent"/>
<arg value="-allowDownload"/>
<arg value="-eulaAccepted"/>
</exec>
This is essentially an installer. When I am trying to run the installer (.exe) from the path, I am getting the following error:
C:\Users\abc\jenkins\install.xml:57: exec returned: 7 (line 57 points to beginning of exec)
I ran ant with verbose option to get more details:

Also I can confirm that my Jenkins slave has access to C:\Users\abc\jenkins\BA\integration_win\Nuze.exe
and I can install manually from that location without any issues. Any idea on where I am erring? I looked up error codes, but generally the tip I got is that there could be some issue with ant configuration. Any pointers? Thanks a ton in advance for the help.
Doesn't look like a ANT issue. "7" is the return code of the program you're running. You need to consult the documentation of the "nuze" program you are running.
Non-zero error codes indicate to ANT that the program has failed and programmers often return different codes to indicate to the calling program what went wrong. Standard OS stuff.
I am not very knowledgeable on this subject but sense there are no other answers I figured I would give it a shot. From looking at similar problems maybe try re-phrasing your xml
<exec executable="cmd" failonerror="true" osfamily="windows">
<arg line="/c ${path.installer} -silent -allowDownload -eulaAccepted"/>
</exec>
I'm been attempting to clone and build a project on my Windows 7 box, like so:
git clone git#github.com:corvec/project-name.git
cd project-name
git submodule init
git submodule update
ant clean
ant resolve
All of the commands up until ant resolve work as expected, which gives me the following error message:

I doubt this is an issue with the configuration specific to the project; I'm not the only developer on this project and the other developers have it working. More likely, it is something related to my system's configuration. They are running Linux and Mac OS, if that makes a difference. I suppose it could potentially be related to some files that are not being tracked by git, but I would think that one of the other developers would have noticed that.
I have tried updating the file paths in build.properties to use an absolute path rather than a relative one, as follows (based on this recommendation):
shared.base=file:///c:/workspace/project-name/core-build
instead of
shared.base=core-build
When I do that, I get the following error message:

I have also attempted to use a new version of Ivy, ivy-2.3.0, but I encounter similar errors.
I think this section is the ivy resolve target:
<target name="resolve" depends="clean-lib, load-ivy" description="--> resolve and retrieve dependencies with ivy">
<echo message="Storing dependencies in lib dir: ${lib.dir}" />
<mkdir dir="lib"/>
<ivy:retrieve />
<ivy:deliver deliverpattern="ivy_delivered.xml" />
</target>
Paths
I've included relevant excerpts of the paths in the build.properties and other related files below:
// build.xml
<property file="build.properties" />
// build.properties
shared.base=core-build
shared.xml=${shared.base}/xml
// build-ivy-targets.xml (imported into build.xml)
<property name="ivy.settings.dir" value="${shared.xml}/ant/ivy" />

I've figured out that the Apache Ivy error message means that somewhere it is failing to parse a directory and is instead reading it as a URL. What steps should I take to fix this?
Ivy on Windows needs the ivy-settings variable to be set differently than on Linux.
Change the line <ivy:settings file="${ivy.settings.dir}/ivysettings.xml" /> to:
<ivy:settings url="file:/C://workspace//project-name//core-build//xml//ant//ivy//ivysettings.xml" />
It's important to note that two things change:
Rather than setting ivy.settings.file, you are setting ivy.settings.url
You are setting an absolute path rather than a relative one.
The problem is that ant is trying to resolve an import from a relative path rather than an absolute location. See this line in your error?
Cannot find C:\workspace\project-name\file:\C:\workspace\project-name\project-name\core-build\xml\ant\build-basic-targets.xml imported from C:\workspace\project-name\build.xml
Make the path to the imported file be a path relative to the build.xml's directory, like "project-name/core-build/xml/ant/basic-build-targets.xml", and your import statement look something like this:
<import file="${basedir}/${shared.base}"/>
I use ant to build my GAE WebApp. This is the datanucleus target:
<target name="datanucleusenhance" depends="compile"
description="Performs enhancement on compiled data classes.">
<enhance_war war="war">
</enhance_war>
</target>
This is the error I got:

How can I use JDO3.0 with GAE1.7.2?
Using the GAE plugin for Intellij, I had to remove the default configured orm directory, and specifically add the higher version libraries.
The GAE SDK is organized as such:
/lib/user/orm (default persistence libraries I removed)
AND
/lib/opt/user/datanucleus/v2
To access this configuration in IntelliJ, from the context menu for my project:
{context menu} -> Open Module Settings -> Libraries -> AppEngine ORM
Use the [-] button to remove the jars within this directory: /lib/user/orm
Use the [+] button to add the jars within this directory: /lib/opt/user/datanucleus/v2
Got the answer. The correct ant target should be:
<target name="datanucleusenhance" depends="compile" description="Performs enhancement on compiled data classes.">
<enhance_war war="war">
<args>
<arg value="-enhancerVersion" />
<arg value="v2" />
</args>
</enhance_war>
</target>
the version is the GAE JDO/JPA plugin version.(Thanks DataNucleus!:)
You seem to be confusing which versions of dependent jars to use. GAE 1.7.2 uses GAE JDO/JPA plugin v2.x, which in turn needs DataNucleus 3.x. You evidently have (various) DataNucleus 1.x jars present.
