In my project I needed to add the option of sending emails I added the library commons-email-1.4 I wrote all the code and tested it. So far everything perfect but when cleaning and building the file . jar of the application, here comes the error.

ant -f C:\\Users\\Clayton\\Documents\\NetBeansProjects\\Agil307 - Dnb.internal.action.name=rebuild clean jar

  273               </dirset>
  274           </src>

If I remove the library commons-email-1.4 and remove the code from the project it builds smoothly.

I don’t know what I can do to solve the problem.

Just for the record I’m using JDK 8.

java netbeans compilation library ant

  • We have little information to work with. "Next error happened while running this line:" and doesn’t say which line. Is it the 269 line of build-impl.xml? Or another line? It would be interesting to post the chunk of build-impl.xml stating which line is 269 (and 929 too, which is the information we have).

  • I will supplement the question with the building lines.

  • netbeans does not show what error the compiler accuses?

  • How many and which libraries you have in the project?

After a few days testing this situation I got a solution, I make use of several libraries and some were added but were not in use, then in case I scanned the used libraries and removed some of them and then tried to carry out the process of cleaning and building, and simply worked now do not know if the project or the compiler accepts a maximum number of libraries and if there was some conflict of some libraries, apparent the removed libraries had no relation to the last added.
