Linux Generate md5 from command line

`echo` would always return with trailing new line char, therefore pass `-n` to
neglect the newline. And so md5sum would received a text from pipe with `-t`
option

 $ echo -n 123456 | md5sum -t

XMage, Adding MutateAbility (2)

Got the ETB triggers, by using the 

Ability abilityEquip = new EntersBattlefieldTriggeredAbility(
    new MutateEffect(Outcome.Mutate)
); 

abilityEquip.addTarget(targetNonHuman);

this.addAbility(abilityEquip);

While the MutatesSourceTriggeredAbility failed to trigger..
or probably it is triggered but there is something in the GameImpl
that treated it different way?

Xmage, Client does not want to Run, as the Card Repository broken or error

If you experience the Card db or repository failure, then simply

Make sure you are in the Mage.Client dir 

$ pwd 

mage/Mage.Client

$ rm -rf db

And then re-run the client,

$ mvn exec:java -Dexec.mainClass="mage.client.MageFrame"

Hope it helps ^^

XMage, Setting Client And Server to TestMode

Mage.Client, go to SessionHandler.java and edit

public static boolean isTestMode() {

	return true;
    //return session.isTestMode();
}

Mage.Server, run is with additional argument set, -testMode=true

$ mvn exec:java -Dexec.mainClass="mage.server.Main" -Dexec.args="-testMode=true"

Happy testing ^^

2. Test the ability of mutated creature

 @Test
    public void testCastMutate() {
        addCard(Zone.BATTLEFIELD, playerA, "Forest", 2);
        addCard(Zone.BATTLEFIELD, playerA, "Plains", 1);
        addCard(Zone.BATTLEFIELD, playerA, "Flourishing Fox",1);
        addCard(Zone.HAND, playerA, "Gemrazer",1);

        setStopAt(1, PhaseStep.BEGIN_COMBAT);

        assertAbility(playerA, "Gemrazer", new CyclingAbility(new ManaCostsImpl("{1}")), true);
        assertHandCount(playerA, 0);
    }

The test result so far so good

Todo:

Ask for the mutation on top or bottom of the targeted non-human creature.

Error at Eclipse build, "... recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0`"

Solution:

Find your .m2 repository dir, in my Linux debian 10 is at ~/.m2

$ find . -name "<your-project-org.xxx.xxx.projectname>"
$ rm -f org/<your-project-org.xxx.xxx.projectname> <-- usually under the name of your project

at the command line of the project, 

$ mvn clean
$ mvn install -DskipTests=true

Reopen eclipse, reference here

select Porject -> Maven -> Update

Have fun ^^
