Hi,

I am trying to compile few dynamically generated aspects programatically. In the program i will contruct a classpath with aspectjrt.jar and aspecttools.jar and other third party jars, which my program depends on. And i compile the dynamically generated aspects as follows,

java -Xmx512m -classpath (followed by all the jars that i have constructed) org.aspectj.tools.ajc.Main E:\MyProject\com\test\aspect\myaspect\hdyb\*.java

When executed as above, it gives the following error,

Exception thrown from AspectJ 1.5.0M5

This might be logged as a bug already -- find current bugs at
  http://bugs.eclipse.org/bugs/buglist.cgi?product=AspectJ&component=Compiler

Bugs for exceptions thrown have titles File:line from the top stack, 
e.g., "SomeFile.java:243"

If you don't find the exception below in a bug, please add a new bug
at http://bugs.eclipse.org/bugs/enter_bug.cgi?product=AspectJ
To make the bug a priority, please include a test program
that can reproduce this exception.

when batch building with classpath:
<classpath>
In the classpath built by aspectj, aspectjtools.jar is not present.

When i try to run the same scenario from command prompt, by explicitly setting in the classpath aspectjtools.jar and aspectjrt.jar and other third party jars, which my stub depends on.. it is compiling successfully and also weaving successfully.

Please let me know, how aspectjtools.jar is considered by ajc in the classpath.

Thanks in advance

I presume aspecttools.jar is a typo though? and it should read aspectjtools.jar.

Take a look in the batch file for ajc, c:\aspectj1.5\bin\ajc.bat to see how ajc puts aspectjtools.jar on the classpath for invoking the compiler.

This was never a bug, more of a question! I'm presuming that Andy's last comment (as of December 2005) solved the problem, if not, please post to the users or dev list.

Thanks.
