Faka futhi ulungiselele iJava ku-Ubuntu 17.04 Zesty Zapus

IJava iyi-complement ebalulekile yokwenza noma ukusebenza kwamathuluzi amaningi ohlelweni futhi ngemuva nje kokukhishwa kwenguqulo entsha ye-Ubuntu, eyi-17.04 Zesty Zapus, kuyadingeka ukuqala faka amaphakheji abalulekile uhlelo lwethu.

Okwamanje i inguqulo enconyiwe yeJava ngu-8 ku buyekeza i-131, esizogxila kukho. I- Ukufakwa kweJava ku-Ubuntu 17.04, ilula ngokuqhathaniswa, singayenza kusuka ku-PPA noma ukuhlanganisa ngqo.

Okokuqala sizoqala ngokufakwa ngendlela elula, okuwukusebenzisa amaphakheji u-Ubuntu asinikeza wona ngqo, yize kuphelelwe yisikhathi, ngoba Ubuntu abubabuyekezi ngesikhathi esifanele lapho kuvela inguqulo entsha.

Ungayifaka kanjani i-JDE ku-Ubuntu 17.04 Zesty Zapus

Into yokuqala kuzoba ukuvula i-terminal bese wenza okulandelayo:

Okokuqala kuzofanele sibuyekeze uhlelo namaphakeji nge:

sudo apt-get update
sudo apt-get upgrade

Ngemuva kwalokho sizoqhubeka siye ku- faka i-JDE no:

sudo apt-get install default-jre

Futhi ngomumo ngalo, sesivele sinendawo yokubulawa kweJava kusistimu yethu.

Ungayifaka kanjani i-JDK ku-Ubuntu 17.04 Zesty Zapus

Ngendlela efanayo, sizovula ukuphela bese senza imiyalo elandelayo:

sudo apt-get update
sudo apt-get upgrade

Futhi ekugcineni siyaqhubeka faka i-Java Development Kit:

sudo apt-get install default-jdk

Ungayifaka kanjani i-Oracle JDK ku-Ubuntu 17.04 Zesty Zapus

Kukhona enye indlela esinikeza ngayo yibhabhi yini iphakethe Oracle isinikeza ngqo futhi singakuthola ukungeza i-PPA de yibhabhi okwethu imithombo.luhlu

Uma sebene-PPA engeziwe, akudingekile ukuyifaka futhi, besizobe siphinda kabili futhi mhlawumbe sidala ukungqubuzana. Okwalabo abangabazayo, bangakuqinisekisa ngomyalo olandelayo:

sudo nano /etc/apt/sources.list

Lapho sesinesiqiniseko sokuthi sizoqhubeka nokwengeza i-PPA kanye ne- faka i-Oracle Java ohlelweni lwethu.

Sizovula ukunqanyulwa bese sisebenzisa:

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 ku-Ubuntu 17.04 Zesty Zapus

IJava isivumela ukuthi sifake izinhlobo ezahlukahlukene ohlelweni, esingakhetha kuzo ukuthi yiluphi uhlobo esizosebenza ngalo ngaphandle kwesidingo sokufaka inguqulo edlule ngaphandle kokukhipha eyedlule.
Ngokusebenzisa ezinye izindlela zokuvuselela, singenza lokhu kulungiselelwa okusivumela ukuphatha izixhumanisi ezingokomfanekiso ezizosetshenziselwa imiyalo ehlukile.

sudo update-alternatives --config java

Izokhombisa izinhlobo ezahlukahlukene zeJava esizifakile, kimi, njengoba bekungukufakwa okusha, nginenguqulo yamanje 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.

Kepha ngokuvamile lapho unenguqulo engaphezu kweyodwa izokhombisa into enjengale:

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

Esivumela ngayo ukuthi sikhethe ngenombolo (iJava version) esizosebenza ngayo.

Lokhu kufake isicelo seminye imiyalo yeJava, efana:

sudo update-alternatives --config javadoc

(umbhalo)

sudo update-alternatives --config javac

(umhlanganisi)

sudo update-alternatives --config java_vm

sudo update-alternatives --config jcontrol

sudo update-alternatives --config jarsigner

(ithuluzi lesiginesha)

Chaza ukuguquguquka kwemvelo kweJava_HOME

I-Java_HOME iyaguquguquka ukunquma indawo yokufakwa kweJava, okusetshenziswa yizinhlelo eziningi ngokuzenzakalela, ngakho-ke, ukusetha lokhu kuguquguquka kuyadingeka ukuthi sazi lapho sifake khona iJava.

Ngomyalo olandelayo singazi:

sudo update-alternatives --config java

Ukuthola le datha vele kuyadingeka ukuyengeza ekugcineni kwaleli fayela, sikwenza ngomyalo olandelayo:

sudo nano /etc/environment

Ngokubheka ukuthi sizongena esikhundleni salokho okusezicaphuni ngendlela esasiyitholile phambilini.

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

Songa nge-ctrl + O bese siphuma nge-ctrl + X.
Ekugcineni siqinisekisa nge:

echo $JAVA_HOME

Futhi i-voila, sizoba nendlela yokulungiswa kwemvelo.

Ekuphetheni, iJava isinikeza ubuningi bezinketho nokwenza ngokwezifiso ukuze sikwazi ukusebenza. Yize iningi lezinyathelo ezichazwe lapha, zimbalwa ezizisebenzisayo, akukaze kube buhlungu ukuthola imininingwane ethe xaxa lapho kunesidingo nangaphezulu lapho uqala ukusebenza ku-Java IDE.
