Problem Building Aggregate - Error Starting Server and No create_db_and_user.sql script

1. What is the problem? Be very detailed.


(NB: This is an updated post - the original was posted, mistakenly, in the Development area)

I'm trying to install Aggregate on a local Raspberry Pi 4.

I've installed Tomcat - and it successfully delivers the test page.

I've installed Postgresql - and run the SQL initialisation commands.

I've had some trouble getting gradlew runAppWar to compile. But I've settled on Java 8 and Gradle 4.5.1 - and it appears to run almost to the end when it comes up with an error 'Error starting server' as the address is already in use.

In the /home/pi/aggregate/build/libs/ directory there is only a single file - 'aggregate.war' but not the 'create_db_and_user.sql' script nor the 'Readme.html' file.

If I use netsat I can see that port 8080 is already in use - which is Tomcat. However I can login to the Tomcat Web Application Manager, stop the application "/" (the test html page) and can copy the war file into tomcat.

sudo cp /home/pi/aggregate/build/libs/aggregate.war /var/lib/tomcat8/webapps/

This alows me to access aggregate at

I can then change the Site Admin password, and upload a form.


  1. I've not got, nor can run, the 'create_db_and_user.sql' script
  2. I can’t get a blank form using the Android ODK app. - "Form listingfailed. getXmlDocument failed while accessing with status code: 404"
  3. None of the icons on the page appear.

Any suggestions as to how to overcome this welcomed!


Error: from gradlew appRunWar script

2. What app or server are you using and on what device and operating system? Include version numbers.

Raspberry Pi 4 - 4GB RAM
Java 8 - openjdk version "1.8.0_212"
Gradle 4.5.1

3. What you have you tried to fix the problem?

See above

4. What steps can we take to reproduce the problem?

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.

During the first attempt to build aggregate there was a failure to open two jar files:-

error: error reading /home/pi/aggregate/libs/gwt-google-maps-v3-1.0.1.jar; error in opening zip file
error: error reading /home/pi/aggregate/libs/gwt-visualization-1.1.2.jar; error in opening zip file

A listing shows them to be very small!!

$ dir ~/aggregate/libs/
-rw-r--r-- 1 pi pi 131 Feb 11 14:00 gwt-visualization-1.1.2.jar
-rw-r--r-- 1 pi pi 131 Feb 11 14:00 gwt-google-maps-v3-1.0.1.jar

So I downloaded them manually from git

$ dir
-rw-r--r-- 1 pi pi 247451 Feb 11 15:41 gwt-visualization-1.1.2.jar
-rw-r--r-- 1 pi pi 424996 Feb 11 15:41 gwt-google-maps-v3-1.0.1.jar
