Re: compiler errors after upgrade to gwt 2.8.0

[Magnus]

Hello Juan,

ok, I understand that eclipse:eclipse is retired.

I installed m2eclipse from the repository site, but after that there is 
nothing about "maven" in the eclipse menus. Even the option "Import 
existing maven projects" is gone!
Even after uninstalling m2eclipse the option didn't come back. So my 
eclipse installation (Mars) seems to be corrupted now?

(I did the installation as recommended by starting eclipse as root first.)

Thanks
Magnus

Ok, I understand that eclipse:eclipse is retired. So I'll switch to m2e.
However, do I have to "clean up" my maven project first, u. e. remove the 
files generated by mvn eclipse:eclipse?

Unfortunately, the documentation for m2e doesn't start from the beginning:
https://www.eclipse.org/m2e/documentation/m2e-development-environment.html

This documentation begins with downloading the SDK, but in the second 
paragraph it refers to installing the plugin with the eclipse UI.
What's the right way then?

Thanks
Magnus

Hello Juan,

sorry, it seems that I didn't point out that my problem is solved!

After executing "mvn eclipse:eclipse" the errors are gone!
So what's wrong with "eclipse:eclipse" then?

Re: doesn't work

[Rogelio Flores]

You need to include the "nocache" script just like your host html file 
does. It looks something like this:

Re: compiler errors after upgrade to gwt 2.8.0

[Juan Pablo Gardella]

I suggest the following:

1) Copy src/ + pom.xml file to another directory. (or remove the project
from the eclipse and delete eclipse related files).
2) Import the project again.

Do not use *mvn eclipse:eclipse, *it's better to use m2e plugin. Let me
know also if mvn clean package works (execute that command in console).

Regards,
Juan

P.S. If you are interested in learning maven, I suggest to read *Better
builds with maven, *it's a bit old but very easy to read and free. You can
pick it from https://maven.apache.org/articles.html

Re: compiler errors after upgrade to gwt 2.8.0

[Magnus]

Hello,

I found that the .classpath file in the root directory of my maven library 
project contains a reference to gwt 2.7.0:


































However, I executed "mvn eclipse:eclipse" and this .classpath file was 
regenerated with the correct gwt version!
Is this the way to go? Sorry, I am still new to maven...

Re: compiler errors after upgrade to gwt 2.8.0

[Magnus]

Hi Thomas,

I have created a new GWT WebApplication project using the eclipse plugin 
("New -> Project -> Web Application Project"), and it compiles fine!
As soon as I add my library project to the build path, the compilation 
error occurrs! So the error must be caused by this library project.

The library project is a maven project with server-side and client-side 
(GWT) code. I upgraded it to GWT 2.8.0 by editing the pom.xml and executing 
"mvn package".
Where should I look next?

Thanks
Magnus

Re: compiler errors after upgrade to gwt 2.8.0

[Thomas Broyer]

Make sure you don't have gwt-user from both 2.7 and 2.8 in your classpath: 
it could be that 2.7 is earlier than 2.8 in the classpath, so the compiler 
sees the Comparator, List, Set and Arrays from 2.7, that don't have stream 
support, and then chokes when parsing Stream (which only exists in 2.8).
