Ku rakib oo ku xir Java on Ubuntu 17.04 Zesty Zapus

Java waa kaabe lama huraan u ah fulinta ama howlgalka aalado badan oo nidaamka ah waxyar ka dib markii la soo saaray nooca cusub ee Ubuntu, kaasoo ah nooca 17.04 Zesty Zapus, waxaa lagama maarmaan ah in la bilaabo ku rakib xirmooyinka muhiimka ah nidaamkayaga.

Waqtigan xaadirka ah nooca lagu taliyay ee Java waa 8 adiga update 131, kaas oo aan diirada ku saari doono. The Ku rakibida Java ee Ubuntu 17.04, way iska fudud tahay, waan sameyn karnaa laga bilaabo PPA ama si toos ah isu ururin.

Marka hore waxaan ku bilaabaynaa rakibida habka ugu fudud, taas oo ah adoo adeegsanaya baakadaha ay Ubuntu si toos ah noo siiso, in kasta oo xoogaa laga duugoobay, maadaama Ubuntu aanu iyaga ku cusbooneysiin waqtiga ku habboon marka nooc cusub u muuqdo.

Sida loo rakibo JDE Ubuntu 17.04 Zesty Zapus

Waxa ugu horeeya waxay noqon doonaan in la furo terminal oo la fuliyo waxyaabaha soo socda:

Marka hore waa inaan cusbooneysiinnaa nidaamka iyo xirmooyinka:

sudo apt-get update
sudo apt-get upgrade

Kadib waxaan usii gudbi doonaa rakibi JDE leh:

sudo apt-get install default-jre

Oo diyaar ayaan ula nahay, waxaan horeyba uheysanay jawva fulinta jawiga nidaamkeena.

Sida loo rakibo JDK Ubuntu 17.04 Zesty Zapus

Si la mid ah, waxaan fureynaa terminal waxaanna fulin doonnaa amarradan soo socda:

sudo apt-get update
sudo apt-get upgrade

Ugu dambeyntiina waxaan kusii soconaa rakibi Qalabka Horumarinta Java:

sudo apt-get install default-jdk

Sida loo rakibo Oracle JDK Ubuntu 17.04 Zesty Zapus

Waxaa jirta waddo kale oo ay na siiso webupd8team waa maxay xirmada Oracle toos noo siisaa waana heli karnaa ku darista PPA de webupd8team kuweena liiska

Haddii ay horeyba u sii raaciyeen PPA-da, muhiim maahan in mar kale lagu daro, kaliya waan soo laba-jibaareynaa oo aan abuuri karnaa isku dhac. Kuwa shakiga qaba, waxay ku xaqiijin karaan amarka soo socda:

sudo nano /etc/apt/sources.list

Hubso in aan sii wadi doonno ku darida PPA iyo rakibi Oracle Java nidaamkayaga.

Waxaan furi doonnaa dhamaadka oo aan fulin doonaa:

sudo apt-get update

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install java-common oracle-java8-installer

U habeynta rakibida Java ee Ubuntu 17.04 Zesty Zapus

Java waxay noo ogolaaneysaa inaan ku helno noocyo kala duwan nidaamka, kaas oo aan ku dooran karno nooca aan ku shaqeyn karno iyadoon loo baahneyn inaan dib u cusbooneysiino qeybtii hore iyadoo aan laga fogeyn mid hore.
Iyada oo loo adeegsanayo beddelaad-beddelasho, waxaan sameyn karnaa qaabeynta noo oggolaaneysa inaan maareyno isku xirnaanta calaamadaha ah ee loo isticmaali doono amarro kala duwan.

sudo update-alternatives --config java

Waxay soo bandhigi doontaa noocyada kala duwan ee Java ee aan rakibnay, kiiskeyga, maadaama ay ahayd rakibid cusub, waxaan haystaa kaliya nooca hadda:

Sólo hay una alternativa en el grupo de enlaces java (provee /usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java</pre>

Nada que configurar.

Laakiin guud ahaan markaad haysato wax ka badan hal nooc waxay soo bandhigi doontaa wax sidan oo kale ah:

There are 3 choices for the alternative java (providing /usr/bin/java)

Selection     PathPriorityStatus 
------------------------------------------------------------
*0 /usr/lib/jvm/java-7-oracle/jre/bin/java1074 auto mode
1/usr/lib/jvm/java-6-oracle/jre/bin/java 1073 manual mode
2 /usr/lib/jvm/java-7-oracle/jre/bin/java  1074 manual mode
3 /usr/lib/jvm/java-8-oracle/jre/bin/java 1072 manual mode

Taas oo noo oggolaaneysa inaan ku dooranno lambarka (nooca Java) aan ku shaqeyno.

Tani waxay sidoo kale codsatay amarrada kale ee Java, sida:

sudo update-alternatives --config javadoc

(dukumenti)

sudo update-alternatives --config javac

(isu geeyay)

sudo update-alternatives --config java_vm

sudo update-alternatives --config jcontrol

sudo update-alternatives --config jarsigner

(qalabka saxiixa)

Qeex isbadalka jawiga JAVA_HOME

JAVA_HOME waa doorsoome lagu ogaanayo meesha uu ku rakiban yahay Java, oo barnaamijyo badan ay u isticmaalaan si aan caadi aheyn, sidaa darteed, si loo dejiyo doorsoomahan waxaa lagama maarmaan ah inaan ogaanno meesha aan ku rakibnay java.

Amarka soo socda waxaan ku ogaan karnaa:

sudo update-alternatives --config java

Haysashada xogtan, waa lagama maarmaan in lagu daro dhamaadka feylkan, waxaan ku sameynaa amarka soo socda:

sudo nano /etc/environment

Anagoo tixgelinayna inaan ku bedelayno waxa kujira xigashooyinka dariiqa aan horay u ogaanay.

JAVA_HOME="/usr/lib/jvm/java-8-oracle"

Waxaan ku keydinaa ctrl + O waxaanna uga baxnaa ctrl + X.
Waxaan ugu dambeyn ku xaqiijinaynaa:

echo $JAVA_HOME

Iyo voila, waxaan heysan doonaa wadada deegaanka.

Gabagabadii, java waxay na siisaa xulasho la'aan iyo u habeyn si aan u awoodno inaan shaqeyno. In kasta oo talaabooyinka halkan lagu sharaxay in yar oo ka mid ahi ay dabaqaan, waligood dhib malahan inaad yeelato macluumaad yar oo dheeri ah markii loo baahdo iyo in ka badan markii aad bilowdo ka shaqeynta Java IDE.
