Setting up the ODK Aggregate environment in Eclipse

[jovaee]

I'm trying to setup the project in Eclipse...

I have been following the CONFIGURE.txt
https://github.com/opendatakit/aggregate/blob/master/CONFIGURE.txt on how
to do this and have installed everything that is listed, configured the
settings as instructed.
I'm trying to complete the Minimal Tomcat8 MySQL/PostgreSQL Eclipse Setup
I'm getting the following error when trying to (10) Select
eclipse-tomcat8, right-click, Google / GWT Compile.
Loading inherited module 'org.opendatakit.aggregate.AggregateUI' [ERROR]
Unable to find 'org/opendatakit/aggregate/AggregateUI.gwt.xml' on your
classpath; could be a typo, or maybe you forgot to include a classpath
entry for source?

I have found this thread
https://groups.google.com/forum/#!searchin/opendatakit-developers/Unable$20to$20find$20$27org$2Fopendatakit$2Faggregate$2FAggregateUI.gwt.xml$27$20on$20your$20classpath$3B$20could$20be$20a$20typo$2C$20or$20maybe$20you$20forgot$20to$20include$20a$20classpath$20entry$20for$20source$3F|sort:relevance/opendatakit-developers/K4e_5EEIeW0/jjHagKbGCwAJ
about a user having similar problems. I suggested that he refresh the
project/workspace all of which I have done. According to this thread after
refreshing the project the required file should be automatically linked.

All the libraries required for the project have been installed and there
are no other errors.
Using Eclipse Mars as described in CONFIGURE.txt
I am using the MySQL setup section for Tomcat.

Any help on this would be appreciated.

OK so I was able to solve the problem. I made the mistake of working in the
wrong workspace, when I switched over to the aggregate one I was able to
GWT compile.

But unfortunately I ran into another issue now, I can't seem to get the
Tomcat server to run. I have Google'd quite a bit and can't seem to figure
out what the cause is.
I have deleted and created new servers, checked that the Java versions
match and cleaning the Tomcat work directory but nothing seems to be
working.

The error I'm getting is:

It looks like there might be some other server listening on port 8080. Or
perhaps another port is in conflict.

Note that if you have installed the Tomcat 8 service, this need to be
stopped before you can run tomcat 8 under Eclipse. Eclipse will use the
same port as the service, but starts it internally.

(and look for other tools that might be using port 8080. E.g., an earlier
install of Tomcat 6 or Apache HTTPD).

OK so I'm sure that the problem is not a port in use error. If this were
the case, when starting the server a popup comes up that says port x is
already in use. But to make sure I checked all ports in use on the PC and
all the required ones were clean.

One thing that I found out in the mean time is that I can start the server
but only as long as it is not hooked up to eclispse-tomcat8. As soon as I
link the two and use "Debug on Server" and choose the server the errors
appear. Does this mean that the compiled eclipse-tomcat8 project may have
errors that causes the start of the server to fail? If this is the case it
would be weird since the entire compile step completes without any errors -
The GWT Compile.

Any thoughts?

[Mitch_S]

Another thing -- after each GWT compile, you need to Refresh your eclipse
project.
This picks up the UI files.

The way I run things (Windows):

(1) download and install the Apache Tomcat 8 MSI installer. Install it.
(2) Go to the Services app (search for it in Run), and verify that the
Apache Tomcat 8 service is set to Manual and is STOPPED.

(3) Configure Eclipse per the instructions.
(4) If you need to begin with a clean website:
(4a) close Eclipse
(4b) delete ..metadata.plugins\org.eclipse.wst.server.core\tmp0 directory
(or any tmpXX directories you find)
(4c) open eclipse. (this deletes the cached website that Eclipse built for
the eclipse-tomcat8 project)
(5) If not yet created, create the server, specifying the port and pointing
it at the install directory from (2)
(6) Open the project settings, and ensure that this server is selected as
the default server for the project.
(7) GWT Compile
(8) Refresh project
(9) Choose the project's Debug > Debug on Server menu option; select the
server you created in (5).

NEVER use the Servers tab's server-right-click Debug or Run options. You
can use the Clean and Publish. I find that these actions do not properly
track the state of your project. And if I use them, I end up having to
repeat step 4 above (you can do step 4 at any time). Step 4 clears the
constructed war structure from Eclipse's brain so it is forced to
reconstruct it from disk.

Or perhaps another port is in conflict.

Note that if you have installed the Tomcat 8 service, this need to be
stopped before you can run tomcat 8 under Eclipse. Eclipse will use the
same port as the service, but starts it internally.

I have deleted and created new servers, checked that the Java versions

[Mitch_S]

No time to create or maintain a dev VM.

It very much looks like you have something listening on port 8080 that is
interfering with the start-up of Tomcat. Try changing the port in the
security.properties and the port in server.xml (in C:\Program Files\Apache
Software Foundation\Tomcat 8.0\conf ) to a different port.

Since I needed to be able to run all of Tomcat 6, 7 and 8 as I was
migrating to Tomcat 8, I also modified my ports in the Server.xml to
support that usage.

Attached are my copies of the server.xml file and the corresponding
security.properties file (from src\main\resources\common) (which you'll
need to edit to specify your hostname).

To update these, you need to:

1. exit Eclipse
2. stop your Tomcat 8 server
3. replace the server.xml in that service (in C:\Program Files\Apache
   Software Foundation\Tomcat 8.0\conf )
4. copy the security.properties to the
   src\main\resources\common location
5. delete the directories under
   .metadata.plugins\org.eclipse.wst.server.core
6. open Eclipse
7. re-run the ant build script for odk-mysql-settings
8. refresh the project
9. delete the existing server (if any is shown)
10. follow the CONFIGURE.txt instructions for creating a new one.

Hopefully this will get your system working. I also noticed that I set the
connection timeout to a very long interval (20 seconds) which might be
needed when running under the debugger.

security.properties (2.41 KB)

getting these errors are very strange.

Another thing -- after each GWT compile, you need to Refresh your eclipse
project.
This picks up the UI files.

The way I run things (Windows):

(1) download and install the Apache Tomcat 8 MSI installer. Install it.
(2) Go to the Services app (search for it in Run), and verify that the
Apache Tomcat 8 service is set to Manual and is STOPPED.

(3) Configure Eclipse per the instructions.
(4) If you need to begin with a clean website:
(4a) close Eclipse
(4b) delete ..metadata.plugins\org.eclipse.wst.server.core\tmp0
directory (or any tmpXX directories you find)
(4c) open eclipse. (this deletes the cached website that Eclipse built
for the eclipse-tomcat8 project)
(5) If not yet created, create the server, specifying the port and
pointing it at the install directory from (2)
(6) Open the project settings, and ensure that this server is selected as
the default server for the project.
(7) GWT Compile
(8) Refresh project
(9) Choose the project's Debug > Debug on Server menu option; select the
server you created in (5).

NEVER use the Servers tab's server-right-click Debug or Run options. You
can use the Clean and Publish. I find that these actions do not properly
track the state of your project. And if I use them, I end up having to
repeat step 4 above (you can do step 4 at any time). Step 4 clears the
constructed war structure from Eclipse's brain so it is forced to
reconstruct it from disk.

OK so I'm sure that the problem is not a port in use error. If this were
the case, when starting the server a popup comes up that says port x is
already in use. But to make sure I checked all ports in use on the PC and
all the required ones were clean.

One thing that I found out in the mean time is that I can start the
server but only as long as it is not hooked up to eclispse-tomcat8. As soon
as I link the two and use "Debug on Server" and choose the server the
errors appear. Does this mean that the compiled eclipse-tomcat8 project may
have errors that causes the start of the server to fail? If this is the
case it would be weird since the entire compile step completes without any
errors - The GWT Compile.

Any thoughts?

Or perhaps another port is in conflict.

Note that if you have installed the Tomcat 8 service, this need to be
stopped before you can run tomcat 8 under Eclipse. Eclipse will use the
same port as the service, but starts it internally.

But unfortunately I ran into another issue now, I can't seem to get

figure out what the cause is.
I have deleted and created new servers, checked that the Java

[mdmahendri]

i have same problem. copy aggregate from my friend, get same error when compile. solved by updating the workspace. but another problem arise, like jovaee mentioned above. i tried solution by Mitch_S but problem still remain. Anyone have a solution?

[LN]

@mdmahendri The build process and toolchain has recently changed to make things consistent across ODK tools and to hopefully make Aggregate easier to get up and running. Please see the new build process and instructions at https://github.com/opendatakit/aggregate.

[mdmahendri]

@LN thanks, but i fork the code and have some modification, so can't do that right now. anyway the issue is now resolved, i change gwt to version 2.7 and it work.
