Intellij/GWT 在没有排列的情况下启动 gwt 应用程序

Question

I want to start my gwt application on dev mode using an external jetty and the gwt compilation server (using -noserver).

Starting the webserver (jetty + gwt war) with 3 permutations (user.agent=safari) takes 250s with options:

• -Dgwt.draftCompile=true
• -Dgwt.compiler.localWorkers=8
• -Dgwt.compiler.optimizationLevel=0

and in the file MyProject.gwt.xml

<set-property name="user.agent" value="safari" />

Then I start the dev mode, and the gwt compilation server does 2 more permutations when I want to refresh the client.

Is it possible to avoid permutations while launching the jetty?

I know that -Dgwt.compiler.skip=true avoid permutations but it doesn't generate the minimum js needed by the gwt compilation server, MyProject directory containing files like MyProject.nocache.js or MyProject.devmode.js is missing so I can't ask the compilation server to do his job while on my browser.

If I use the option -Dgwt.compiler.skip=true, my webserver starts in 30s but I am stuck.

I don't know why gwt needs to do permutations while launching the webserver, isn't that the gwt compilation server's job on dev mode?

Answer 1

You can avoid multiple permutation by collapsing all properties in the gwt.xml which will merge all permutations into one

<collapse-all-properties/>

Answer 2

This sounds like your project is not set up correctly. What version of GWT are you using. Is this dev mode "Super Dev Mode" or the old dev mode?

Is it possible to avoid permutations while launching the jetty?

There should not be permuations being generated when the web server (jetty) launches. Only when you open the page in your browser should the code server run the GWT compiler to compile the module and then bind to one user agent based on your browser type, and that 1 permutation is then compiled.
