Probably a bug within the ImageJ Plugins->Compile_and_Run... method

Dear all (probably Wayne),

I have the following plugin file (Call_Demo.java):

public class Call_Demo

{

public static String
method1(String arg1)

{

return
"method1"+"("+arg1+")";

}

}

That I call with the following plugin (My_Plugin.java):

import ij.*;

import ij.plugin.*;

public class My_Plugin implements PlugIn

{

public void run(String arg)

{

IJ.log(Call_Demo.method1("arg1"));

}

}

In this case everything is working fine: i.e. I get the result
"method1(arg1)" within the log window when I compile both plugins with the
ImageJ Plugins->Compile_and_Run... method.

If I then pack the Call_Demo.java (and Call_Demo.class) file (with the
needed plugins.config file) within a jar file having no "_" within its name
(for example test.jar), I cant see the "Call_Demo" plugin within the ImageJ
plugin menus (in agreement to what is described here:
http://imagejdocu.tudor.lu/doku.php?id=howto:plugins:howto_create_an_imagej_
plugin_jar_file) but when compiling My_Plugin.java with the the ImageJ
Plugins->Compile_and_Run... method everything is still working fine (i.e. I
get the result "method1(arg1)" within the log window).

But if I now rename the jar file (within which the Call_Demo.java,
Call_Demo.class and plugins.config file are packed) to "test_it.jar", I can
now see "Call_Demo" plugin within the ImageJ plugin menus (in agreement to
what is described here:
http://imagejdocu.tudor.lu/doku.php?id=howto:plugins:howto_create_an_imagej_
plugin_jar_file) but when compiling My_Plugin.java with the the ImageJ
Plugins->Compile_and_Run... method I get now the error: cannot find symbol
symbol : variable Call_Demo location: class My_Plugin
IJ.log(Call_Demo.method1("arg1"));.

Nevertheless, if I put the "test_it.jar" and "My_Plugin.java" within the
plugin folder of Fiji, Drag&Drop "My_Plugin.java" file within the Fiji
window in order to open a Script widow where I press Run, the
"My_Plugin.java" is then correctly compiled.

And if I finally put the "My_Plugin.class" file obtained within Fiji inside
of the ImageJ plugin folder I can then as well correctly run the
"My_Plugin.class" plugin.

I thank you very much in advance for your help about this issue.

Kindest regards,

Philippe

Bien cordialement,

Philippe

Re: Probably a bug within the ImageJ Plugins->Compile_and_Run... method

The Plugins>Compile and Run command does not normally add jar files with “_” in their names to the javac class path, which means the plugin your are compiling cannot access the classes in a jar file that has an “_” in its name. As a workaround, put the jar file that needs to be accessed in the plugin/jars folder. With the latest ImageJ daily build (1.51e13), all jar files in plugins/jars are added to the javac class path.
