Processing Build failed
Hi,
I've a build issue with processing:
jvme@Johan-linux-Mint ~/Downloads/processing/build
$ ant run
...
preproc:
BUILD FAILED /home/jvme/Downloads/processing/build/build.xml:274: The following error occurred while executing this line: /home/jvme/Downloads/processing/build/build.xml:324: The following error occurred while executing this line: /home/jvme/Downloads/processing/java/build.xml:37: Problem: failed to create task or type antlr Cause: the class org.apache.tools.ant.taskdefs.optional.ANTLR was not found. This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in -/usr/share/ant/lib -/home/jvme/.ant/lib -a directory added on the command line with the -lib argument
Do not panic, this is a common problem. The commonest cause is a missing JAR.
This is not a bug; it is a configuration problem
Total time: 7 seconds
I've followed the build instructions.
Can anyone help me with is?
Best Regards,
Johan
Answers
This is because you don't have antlr external library. To deal with this problem you need to install ant optional tasks which can deal with external libraries and ant core. You can use
sudo apt-get install ant-optionalto install it.
