install Gradle and Groovy on Mint 17

August 6, 2014|gradle, groovy, mint, ubuntu|電腦編程

Initially found a script to install gradle, but later on found out that script is not required because groovy environment manager can also install gradle.

#!/bin/bash
# installs to /opt/gradle
# existing versions are not overwritten/deleted
# seamless upgrades/downgrades
# $GRADLE_HOME points to latest *installed* (not released)

wget -N http://services.gradle.org/distributions/gradle-${gradle_version}-all.zip -P /tmp/
sudo unzip -q /tmp/gradle-${gradle_version}-all.zip -d ${gradle_path}
sudo ln -sfn gradle-${gradle_version} ${gradle_path}/gradle
sudo printf "export GRADLE_HOME=${gradle_path}/gradle/\nexport PATH=\$PATH:\$GRADLE_HOME/bin" > /etc/profile.d/gradle.sh

今早回到公司, 係pantry有個強國同事問我知唔知雲南地震. 其實我係有D 老派, 我lunch time 有時間就睇下appledaily 個apps, 放工回家or 臨訓係床上先掃下副刊財經港聞. instant news 反而係fb news feed. 突發野朋友間share / like 已經會知道. 今晚回家後再check 多一次news feed, 高雄有朋友RIP, 雲南真係冇, 唔知係因為強國天災人禍太多已經麻目, 又或者係fb 白痴既filter 冇display 個d 相關news feed. 不過強國咁勁, 抄左周老虎家都夠震災有突, 而且他們相信災難興邦, 又實在沒有什麼好擔心的.
