Reuses caches on SDM relaunch, makes first compile ~4x faster. Previously MinimalRebuildCache instances were not persisted or loaded from disk at all and a new PersistentUnitCache was built from scratch for each SDM launch. Now SDM takes care to choose a location for its PersistentUnitCache in a way that will be consistent when SDM is relaunched in the same project and targetting the same module. Going further MinimalRebuildCache instances are now read from disk at the beginning and persisted to disk after every compile. Similarly these cache instances are saved to a folder whose name is consistent for the same project and module and are saved to a file named consistently using a combination of project, module and compiler version. Because these caches are tied to the compiler version and because the managed objects are tied to .java class modification dates, they should always be correct. But in the event that something does become corrupt there is now a SDM button to clear disk caches.

## GWT
GWT is the official open source project for GWT releases 2.5 and onwards.
In this document you have some quick instructions to build the SDK from source code and to run its tests.
For a more detailed documentation visit our web site. If you are interested in contributing with the project, please read the Making GWT better section.
In order to build GWT, java and ant are required in your system.
Optional: if you want to compile elemental you need python and g++ installed.
You need the gwt-tools checked out and up-to-date, and it will be placed by default at ../tools. You can override the default location using the GWT_TOOLS environment variable or passing -Dgwt.tools= argument to ant.
Note: that you need svn to checkout gwt-tools
To create the SDK distribution files run:
$ ant clean elemental dist-dev
or if you don't have python and g++ just run
$ ant clean dist-dev
Then you will get all .jar files in the folder build/lib and the redistributable file will be: build/dist/gwt-0.0.0.zip
if you want to specify a different version number run:
$ ant elemental clean dist-dev -Dgwt.version=x.x.x
To compile everything including examples you have to run
$ ant clean elemental dist
In GWT we have some conventions so as all code written by contributors look similar being easier to review.
After you make any modification, run this command to compile everything including tests, to check APIs, and to verify code style. It shouldn't take longer than 3-4 minutes.
$ ant compile.tests apicheck checkstyle -Dprecompile.disable=true
Previously to run any test you have to set some environment variables to guarantee that they are run in the same conditions for all developers.
In a Unix like platform you can use the export command:
$ export TZ=America/Los_Angeles ANT_OPTS=-Dfile.encoding=UTF-8
But in Windows™ you have to set the time-zone in your control panel, and the environment variables using the command set.
Finally you can run all test suites with the following command, but be prepared because it could take hours, and probably it would fail because of timeouts, etc.
$ ant test
Thus, you might want to run only certain tests so as you can focus on checking the modifications you are working on.
GWT build scripts use specific ant tasks and a bunch of system properties listed in the following table to specify which tests to run and how.
For instance to run the task test in the module user you have to change to the user folder and run ant with the task as argument, adding any other property with the -D flag:
$ ( cd user && ant test -Dtest.emma.htmlunit.disable=true ; cd .. )
| Module | Task | Property to skip |
|---|---|---|
| dev | test | test.dev.disable |
| codeserver | test | test.codeserver.disable |
| user | test | test.user.disable |
| user | test.nongwt | test.nongwt.disable |
| user | test.dev.htmlunit | test.dev.htmlunit.disable |
| user | test.web.htmlunit | test.web.htmlunit.disable |
| user | test.draft.htmlunit | test.draft.htmlunit.disable |
| user | test.nometa.htmlunit | test.nometa.htmlunit.disable |
| user | test.emma.htmlunit | test.emma.htmlunit.disable |
| user | test.coverage.htmlunit | test.coverage.htmlunit.disable |
| user | test.dev.selenium | test.dev.selenium.disable |
| user | test.web.selenium | test.web.selenium.disable |
| user | test.draft.selenium | test.draft.selenium.disable |
| user | test.nometa.selenium | test.nometa.selenium.disable |
| user | test.emma.selenium | test.emma.selenium.disable |
| requestfactory | test | |
| elemental | test | |
| elemental | test.nongwt | |
| elemental | test.dev.htmlunit | |
| elemental | test.web.htmlunit | |
| tools | test |
Additionally you can utilize some variables to filter which test to run in each task:
| Module | Task | Properties | Default |
|---|---|---|---|
| dev/core | test | gwt.junit.testcase.dev.core.includes | **/com/google/**/*Test.class |
| gwt.junit.testcase.dev.core.excludes | |||
| user | test | gwt.junit.testcase.includes | **/*Suite.class |
| user | test.nongwt | gwt.nongwt.testcase.includes | **/*JreSuite.class |
| gwt.nongwt.testcase.excludes | |||
| user | test.web.* test.draft.* test.nometa.* | gwt.junit.testcase.web.includes | **/*Suite.class |
| gwt.junit.testcase.web.excludes | **/*JsInteropSuite.class,**/*JreSuite.class,***/OptimizedOnly* | ||
| user | test.dev.* test.emma.* | gwt.junit.testcase.dev.includes | **/*Suite.class |
| gwt.junit.testcase.dev.excludes | **/*JsInteropSuite.class,**/*JreSuite.class,***/OptimizedOnly* |
Run all tests in dev
$ ( cd dev && ant test ; cd .. )
Note: that the last `cd ..' is only needed in Windows.
There is another option to do the same but without changing to the module folder. We have to specify the module as the ant task, and the task as a target argument.
$ ant dev -Dtarget=test
Run all tests in codeserver
$ ( cd dev/codeserver && ant test )
or
$ ant codeserver -Dtarget=test -Dtest.dev.disable=true
Note: that we disable dev tests because code server depends on dev and we don`t want to run its tests.
Run all tests in elemental:
$ ( cd elemental && ant test.nongwt )
or
$ ant elemental -Dtarget=test -Dtest.dev.disable=true -Dtest.user.disable=true
Note: that we have to disable dev and user tests because elemental depends on both.
Run all tests in tools
$ ant tools -Dtarget=test -Dtest.dev.disable=true -Dtest.user.disable=true
Run only the JsniRefTest in dev
$ ant dev -Dtarget=test \
-Dgwt.junit.testcase.dev.core.includes="**/JsniRefTest.class"
Run a couple of tests in dev
$ ant dev -Dtarget=test \
-Dgwt.junit.testcase.dev.core.includes="**/JsniRefTest.class,**/JsParserTest.class"
Note: that you have to use regular expressions separated by comma to select the test classes to execute.
Run all Jre tests in user, they should take not longer than 3min. We have two ways to run them. Although the second case is more complex it is here to know how disable properties work.
$ ( cd user && ant test.nongwt )
or
$ ant user -Dtarget=test -Dtest.dev.disable=true \
-Dtest.dev.htmlunit.disable=true \
-Dtest.web.htmlunit.disable=true \
-Dtest.coverage.htmlunit.disable=true \
-Dtest.dev.selenium.disable=true \
-Dtest.draft.htmlunit.disable=true \
-Dtest.draft.selenium.disable=true \
-Dtest.emma.htmlunit.disable=true \
-Dtest.emma.selenium.disable=true \
-Dtest.nometa.htmlunit.disable=true \
-Dtest.nometa.selenium.disable=true \
-Dtest.web.selenium.disable=true
Note: that we have to set all disable variables but test.nongwt.disable
Run certain Jre tests in the user module.
$ ( cd user && ant test.nongwt -Dgwt.nongwt.testcase.includes="**/I18NJreSuite.class" )
Run all GWT tests in user using htmlunit in dev mode.
$ ( cd user && ant test.dev.htmlunit )
