The following JDKs are installed:
We provide the function
jdk_switcher, available as a setup command, to choose the JDK for your builds.
This function can take one of two commands,
usewill select the given JDK by changing the java executables, and setting JAVA_HOME and JRE_HOME.
homewill print out the value of JAVA_HOME for a given JDK (but make no modifications).
The valid values for
home are openjdk7, oraclejdk7, and oraclejdk8.
By default, OpenJDK 7 is selected. The following would be the resulting Java version, JAVA_HOME, and JRE_HOME for each JDK:
jdk_switcher home openjdk7 # /usr/lib/jvm/java-7-openjdk-amd64 jdk_switcher use openjdk7 echo $JAVA_HOME # /usr/lib/jvm/java-7-openjdk-amd64 echo $JRE_HOME # /usr/lib/jvm/java-7-openjdk-amd64/jre java -version # java version "1.7.0_65" # OpenJDK Runtime Environment (IcedTea 2.5.3) (7u71-2.5.3-0ubuntu0.14.04.1) # OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)
jdk_switcher home oraclejdk7 # /usr/lib/jvm/java-7-oracle jdk_switcher use oraclejdk7 echo $JAVA_HOME # /usr/lib/jvm/java-7-oracle echo $JRE_HOME # /usr/lib/jvm/java-7-oracle/jre java -version # java version "1.7.0_72" # Java(TM) SE Runtime Environment (build 1.7.0_72-b14) # Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)
jdk_switcher home oraclejdk8 # /usr/lib/jvm/java-8-oracle jdk_switcher use oraclejdk8 echo $JAVA_HOME # /usr/lib/jvm/java-8-oracle echo $JRE_HOME # /usr/lib/jvm/java-8-oracle/jre java -version # java version "1.8.0_25" # Java(TM) SE Runtime Environment (build 1.8.0_25-b17) # Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
The following tools are preinstalled in our virtual machine. You can add them to your setup or test commands to start your build:
Scala , Clojure, Groovy and other JVM based languages should be running fine on our systems as well. Let us know if you find something that doesn’t work as expected
Codeship automatically caches the
$HOME/.m2/repository directories between builds to optimize build performance. You can read this article to learn more about the dependency cache and how to clear it.
