IJava sisincedisi esibalulekileyo sokwenza okanye ukusebenza kwezixhobo ezininzi kwinkqubo kwaye kungekudala nje emva kokuba kukhutshiwe inguqulelo entsha Ubuntu, engu-17.04 Zesty Zapus, kubalulekile ukuqala faka iipakeji ezifanelekileyo kwinkqubo yethu.
Okwangoku Inguqulelo ecetyiswayo yeJava ngu 8 kweyakho Hlaziya i131, esiza kugxila kuyo. Inkqubo ye- Ukufakwa kweJava kwi-Ubuntu 17.04, ilula ngokulula, singayenza ukusuka kwi-PPA okanye ukudibanisa ngokuthe ngqo.
Kuqala siza kuqala ngofakelo ngendlela elula esebenzisa iipakeji esizinikwa ngu-Ubuntu ngokuthe ngqo, nangona iphelelwe lixesha, kuba Ubuntu ayizihlaziyi ngexesha elifanelekileyo xa kuvela uhlobo olutsha.
Uyifaka njani iJDE kwi-Ubuntu 17.04 Zesty Zapus
Into yokuqala iya kuba kukuvula i-terminal kwaye wenze oku kulandelayo:
Kuqala kuya kufuneka sihlaziye inkqubo kunye neephakeji nge:
sudo apt-get update sudo apt-get upgrade
Emva koko siya kuqhubela phambili faka iJDE no:
sudo apt-get install default-jre
Kwaye silungile ngayo, sele sinayo imeko yokuphunyezwa kweJava kwinkqubo yethu.
Uyifaka njani i-JDK kwi-Ubuntu 17.04 Zesty Zapus
Ngendlela efanayo, siya kuvula i-terminal kwaye senze le miyalelo ilandelayo:
sudo apt-get update sudo apt-get upgrade
Kwaye ekugqibeleni siyaqhubeka faka iKhithi yoPhuculo lweJava:
sudo apt-get install default-jdk
Uyifaka njani i-Oracle JDK kwi-Ubuntu 17.04 Zesty Zapus
Kukho enye indlela esinika ngayo yeebsweb yintoni iphakheji Oracle isinika ngokuthe ngqo kwaye sinokuyifumana ukongeza iPPA de yeebsweb eyethu imithombo yolwazi
Ukuba sele benayo iPPA eyongeziweyo, akukho mfuneko yokuba uyongeze kwakhona, siya kuba siphinda-phinda kwaye mhlawumbi sidala ungquzulwano. Kulabo banokungabaza, banokuyiqinisekisa ngalo myalelo ulandelayo:
sudo nano /etc/apt/sources.list
Nje ukuba siqiniseke ukuba siya kuqhubeka ukongeza iPPA kunye faka iOracle Java kwinkqubo yethu.
Siza kuvula ukupheliswa kwaye senze:
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install java-common oracle-java8-installer
Ukwenza ngokwezifiso ukufakwa kweJava kwi-Ubuntu 17.04 Zesty Zapus
IJava isivumela ukuba sibe neenguqulelo ezahlukeneyo ezifakwe kwisistim, esinokuthi sikhethe ukuba yeyiphi na inguqulelo esiza kusebenza kuyo ngaphandle kwesidingo sokubuyisela ingxelo yangaphambili ngaphandle kokuphelisa eyangaphambili.
Ngokusebenzisa hlaziya-ezinye iindlela, sinokwenza olu luqwalaselo lusivumela ukuba silawule amakhonkco okomfuziselo aya kuthi asetyenziselwe imiyalelo eyahlukeneyo.
sudo update-alternatives --config java
Izakubonisa iinguqulelo ezahlukeneyo zeJava esizifakileyo, kwimeko yam, njengoko yayilufakelo olutsha, ndinenguqulo yangoku kuphela:
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.
Kodwa ngokubanzi xa unenguqulo engaphezulu kwesinye iya kubonisa into enje:
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
Ukusivumela ukuba sikhethe ukuba leliphi inani (uguqulelo lweJava) lokusebenza.
Oku kuyasetyenziswa kweminye imiyalelo yeJava, enje:
sudo update-alternatives --config javadoc
(uxwebhu)
sudo update-alternatives --config javac
(umqokeleli)
sudo update-alternatives --config java_vm
sudo update-alternatives --config jcontrol
sudo update-alternatives --config jarsigner
(isixhobo sokutyikitya)
Chaza imeko ye Java_HOME eyahlukileyo kwimeko-bume
I-Java_HOME ngumahluko wokumisela indawo yofakelo lweJava, ezisetyenziswa ziinkqubo ezininzi ngokungagqibekanga, ke ngoko, ukuseta oku kwahluka kuyafuneka ukuba sazi apho sifake khona iJava.
Ngalo myalelo ulandelayo sinokwazi:
sudo update-alternatives --config java
Ukuba nale datha, kuya kufuneka uyongeze esiphelweni sale fayile, siyenza ngalo myalelo ulandelayo:
sudo nano /etc/environment
Ukuthathela ingqalelo into yokuba siza kuthatha indawo yezicatshulwa kunye nendlela esasiyifumene ngaphambili.
JAVA_HOME="/usr/lib/jvm/java-8-oracle"
Sigcina nge-ctrl + O kwaye siphume nge-ctrl + X.
Ekugqibeleni siqinisekisa nge:
echo $JAVA_HOME
Kwaye nge-voila, siya kuba nendlela yendalo esingisiweyo.
Ukuqukumbela, iJava ibonelela ngokungapheliyo kokhetho kunye nokwenza ngokwezifiso ukuze sikwazi ukusebenza. Nangona uninzi lwamanyathelo achazwe apha, bambalwa abawasebenzisayo, akukaze kubuhlungu ukuba nolwazi olongezelelekileyo xa kufuneka kwaye nangakumbi xa uqala ukusebenza kwi-Java IDE.
