Drools beginner - unable to resolve method using strict-mode
by Stefan Schuster
Hi,
I'm new to drools, and I made my first steps using the very nice
video-tutorial "Build Pong in 13 minutes using JBoss Drools" found here:
http://www.youtube.com/watch?v=Omj4PR3v-nI
Eclipse shows building errors, but Pong start anyway. What does this error
mean?
in move.drl there is following rule:
*<rule "Move Bat Up" timer(expr: bat.speed, bat.speed) no-loop when*
* ui : PongUI( ready == true )*
* ( KeyPressed( keyText == "A" ) and bat : Bat( playerId ==
PlayerId.PlayerOne, y > pconf.padding + pconf.sideLineWidth )*
* or*
* KeyPressed( keyText == "K" ) and bat : Bat( playerId ==
PlayerId.PlayerTwo, y > pconf.padding + pconf.sideLineWidth ) ) *
* td : TableDirty( ) *
*then *
* tableG = ui.getTablePanel().getTableG();*
* tableG.setColor( Color.BLACK ); // background*
* tableG.fillRect( bat.x, bat.y, bat.width, bat.height );*
* *
* modify( bat ) { y = bat.y - 2 };*
* tableG.setColor( Color.WHITE ); // background*
* tableG.fillRect( bat.x, bat.y, bat.width, bat.height ); *
* modify( td ) { dirty = true };*
*end*
the error message is:
[Error: unable to resolve method using strict-mode:
org.drools.spi.KnowledgeHelper.td<http://org.drools.spi.knowledgehelper.td/>
()]
[Near : {... @Modify with( td ) { dirty = true }; ....}]
in another File (ui.drl) TableDirty is defined:
*declare TableDirty*
* @propertyReactive*
* dirty : boolean*
*end*
Any ideas what this error message means? And why can I start pong despite
this error?
Thanks a lot for helping me

conways game of life
by Mark Proctor
For anyone looking for a good and complex example on how to write rules
properly, please look at Conways Game of Life in drools-examples, for
extra bonus points compare it to the old version in M1. You'll see
nearly all the logic is moved from java to the drl and we have removed
the need for nested objects by using objects relaitionally, which also
allows us to exploit cross products to drive the application.

KieScanner cannot fetch LATEST Jars from custom Maven repository - Maven - 3.6.3
by suriya devan
Hello All,
I am using a drool version 7.x. I am able to get KieScanner to work on my
local maven repository using "LATEST". But everytime I update the rules on
workbench, I have to manually run mvn install in order to update my local
repository so that KieScanner can pickup the changes. Is that how it is? Or
is it possible to force a download every time the scanner runs?
I need to fetch the latest jars from my custom repo.
My configuration
KieServices ks = KieServices.Factory.get();
ReleaseId releaseId = ks.newReleaseId( "com.test", "poc", "LATEST" );
KieContainer kContainer = ks.newKieContainer(releaseId);
KieScanner kieScanner = ks.newKieScanner(kContainer);
kieScanner.start( 10000L );
Scanner scanner = new Scanner(System.in);
while (true) {
kieScanner.scanNow();
String line = scanner.nextLine();
runRule(kContainer);
}}
I have configured my custom repo in maven confg settings file. . But no luck
<profile>
<id>development</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<repositories>
<repository>
<id>customRepo</id>

</repository>
</repositories>

</activeProfiles>
Any one please advise to resolve the issue?
