Bagaimana cara membuat file .jar yang dapat dieksekusi menggunakan perintah Linux dan tanpa Pintasan Eclipse?
Diterbitkan: 2022-01-03
Sejauh ini bagi saya sangat mudah untuk mengklik kanan di Eclipse IDE dan membuat file .jar yang dapat dieksekusi dengan beberapa klik sederhana. Minggu lalu saya harus membuat file .jar file manually di node Digital Ocean tempat kami biasanya menghosting banyak layanan.
Butuh beberapa waktu untuk membuat file .jar secara langsung hanya dengan menggunakan perintah tetapi akhirnya setelah 10 menit, file .jar yang dapat dieksekusi sudah siap.
Jika Anda memiliki pertanyaan di bawah ini maka Anda berada di tempat yang tepat:
- Cara terbaik untuk membuat file jar di baris perintah Linux
- Bagaimana cara membuat file jar dapat dieksekusi di Linux?
- Bagaimana cara mengkompilasi file jar di Linux?
- Bagaimana cara membuat file JAR Linux dapat dieksekusi?
- Bagaimana Cara Membuat dan Mengeksekusi File .Jar di Terminal Linux?
Mari kita mulai:
Langkah-1) Pastikan Anda menginstal Java di sistem Linux
Jika Java sudah terinstal maka langsung ke step-4 . Coba jalankan perintah javac dan jika Anda melihat hasil di bawah ini maka tidak ada instalasi Java di Host.

root @ localhost : ~ / java / src # javac Command 'javac' not found , but can be installed with : apt install openjdk - 11 - jdk - headless apt install default - jdk apt install openjdk - 8 - jdk - headless apt install ecj |
Langkah-2) Instal Java di host linux

Langkah-3) Verifikasi di Java
Coba jalankan lagi perintah di bawah ini dan Anda akan melihat detail Java yang diinstal.

root @ localhost : ~ / crunchify / src / package # which java / usr / bin / java root @ localhost : ~ / crunchify / src / package # java -version openjdk version "11.0.1" 2018 - 10 - 16 OpenJDK Runtime Environment ( build 11.0.1 + 13 - Ubuntu - 3ubuntu3.18.10.1 ) OpenJDK 64 - Bit Server VM ( build 11.0.1 + 13 - Ubuntu - 3ubuntu3.18.10.1 , mixed mode , sharing ) |
Langkah-4)
Berikut adalah daftar perintah yang perlu Anda jalankan untuk membuat file .jar yang dapat dieksekusi.

Dan Anda sudah siap.
Seperti yang Anda lihat di atas, Anda memiliki file Crunchify.jar yang dibuat di bawah folder /root/crunchify/src/build .
