Cannot run program "keytool"

[nclavaud]

I'm running Processing 3.2.1 on Ubuntu 16.04.1 and I have installed Android mode 3.0.1 using the Contribution Manager. I have been prompted to install the Android SDK and I end up with Android SDK 6.0 (23) installed.

When trying to run the Getting started tutorial app on my device, I get the build error below, complaining file java/bin/keytool cannot be found.

BUILD FAILED
/home/processing/sketchbook/modes/AndroidMode/sdk/tools/ant/build.xml:958: The following error occurred while executing this line:

Update it if necessary, or manually execute the following command:

    ...
    at processing.mode.android.AndroidEditor$16.run(AndroidEditor.java:553)

Indeed the file does not exist on my machine.

Did I miss something?

Actually the keytool executable is available at /usr/bin/keytool on my machine.

$ whereis keytool
keytool: /usr/bin/keytool /usr/share/man/man1/keytool.1.gz

I could alias it, and managed to build the example application succesfully.

$ ln -s /usr/bin/keytool /home/processing/processing-3.2.1/java/bin/keytool

This step is not documented. Should we document it in Getting started tutorial?

@nclavaud thanks for your report, and the workaround. The mode should not try to run a missing keytool binary though. Will look into it!

I have experienced this on Ubuntu 16.04 as well. I had to install the java SDK though to get access to the key tool and perform the above workaround.

Looks like this is due to an omission in Processing's build file, which is removing keytool on Windows and Linux https://github.com/processing/processing/issues/3288
