cannot find symbol
Hi People.
I am trying to compile some files with ant but am getting the following
errors.
[javac] D:\Stats\src\org\selectbf\gui\ConfigurationDialog.java:32: package
org.eclipse.swt.widgets does not exist
[javac] import org.eclipse.swt.widgets.Text;

[javac] symbol : class TabItem
[javac] location: class org.selectbf.gui.ConfigurationDialog

In total there are 100 of these errors :-o.
As I have never used ant before, is there anything I can do to fix this?
Thanks in advance.

AW: ****SPAM**** cannot find symbol
Posted by "Knuplesch, Juergen" <Ju...@icongmbh.de>.
Obviously you dont have some necessary jar files on your compile classpath.
package org.eclipse.swt.widgets
You probably have this files on your Eclipse classpath / buildpath.
You have to add allof them to your compile classpath (see reference of javac task)
If you use Eclipse: You could also use Ant4Eclipse to get the classpath that Eclipse is using.
Greetings Juergen

Re: cannot find symbol
Posted by David Weintraub <qa...@gmail.com>.
It looks like they're defining a classpath called "classpath" (easy enough
to remember). Have you looked at the Ant documentation at <
http://ant.apache.org/manual/index.html>?
The "path" called "classpath" is defined by all of the jarfiles located
under the directory called ${lib_dir}. You will have to look at your
build.xml file to see where ${lib_dir} is defined. You should see something
like this:
<property name="lib_dir" value="some_directory"/>
It is similar to a Windows batch script setting an environment variable:
set lib_dir=some_directory
Make sure all of the jarfiles you need are located inside this ${lib_dir}.
There is one more property called ${java.class.path} that is also added to
this classpath. Is this defined anywhere inside your buld.xml file?
The question is whether you're suppose to compile with java.class.path or
classpath. There isn't much explanation which one you should use.
If you're suppose to compile with classpath, you need to do this:
<javac
srcdir="${src.dir}"
destdir="${dest.dir}"
*classpathref="classpath"*/>
Otherwise, if you're suppose to use java.class.path, you would do this:
<javac
srcdir="${src.dir}"
destdir="${dest.dir}"
*classpath="${java.class.path}"*/>

Re: cannot find symbol
Posted by Hungry Snail <ce...@hotmail.com>.
Hi David,
Many thanks for the reply.
I am using a script that someone sent me, this is the first time I have ever
attempted to compile anything :).
<path id="classpath">
<fileset dir="${lib_dir}">
<include name="*.jar" />
</fileset>
<pathelement path="${java.class.path}" />
</path>
This is what is in the build.xml
by looking at that I am guessing that the class path isnt actually defined?
Regards

Re: cannot find symbol
Posted by David Weintraub <qa...@gmail.com>.
This isn't an Ant error as much as a "javac" command error. What you're
being told is that a particular program is trying to resolve a symbol, but
can't find the reference to that symbol. For example, these particular
classes are defined in a jarfile called something like
org.eclipse.swt.<shell>.<OS>_<version>.jar which lives in your Eclipse
installation. On my system it is called
org.eclipse.swt.gtk.linux.x86_64_3.4.1.v3449c.jar. On a Windows system, it
might be org.eclipse.swt.win32.win32.x86_3.3.0.v3346.jar.
When you run the <javac> task, you must make sure this jarfile is in the
classpath.
There are multiple ways of setting the classpath when you compile using the
<javac> command. One is to set the "classpath" parameter itself. Another is
to use a "reference" to set the classpath, and then use the classpathref
parameter. This is nicer since it gives you a bit more flexibility. Here I'm
defining a classpath called "class.path":
<path id="class.path">
<fileset dir="${basedir}/lib">
<include name="**/*.jar"/>
</fileset>
<pathelement file="${some.other.jar.file.I.need"/>
</path>
Now, you can add and subtract jarfiles your build depends upon by simply
adding them to the ${basedir}/lib directory. You no longer have to modify
your build.xml file every time someone adds a new jarfile dependency. You
can compile like this:
<javac
srcdir="${src.dir}"
dest="${target.dir}/classes"
*classpathref="class.path"*/>
Now, you're referencing the path "class.path" as your classpath for your
"javac" command.
Another way is to use a sub-task:
<javac
srcdir="${src.dir}"
destdir="${target.dir}/classes">
* <classpath>**
<fileset dir="${basedir}/lib">
<include name="**/*.jar"/>
</fileset>
<path refid="class.path2"/>
<pathelement file="${some.other.jar.file.I.need"/>
</classpath>*
</javac>
This allows you to build more complex classpaths that might be possible with
a single reference. Notice that I am using fileset, pathelement, and even a
reference to a previously defined path called "class.path2".
How do you compile your code now? Are you using a script? If so, what is
the classpath used by the javac command in your script? That'll help you
understand what should be in your classpath when you run <javac>.
