Installer une JVM à la main sans les droits root.

Je copie-colle l'astuce :

JDK is not available as a portable ZIP file, unfortunately. However, you can follow these steps:

• Create working JDK directory (C:\JDK in this case)
• Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe)
• Download and install 7-Zip (or download 7-Zip portable version if you are not administrator)
• With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK
• Execute the following commands in cmd.exe:
  • cd C:\JDK.rsrc\1033\JAVA_CAB10
  • extrac32 111
• Unpack C:\JDK.rsrc\1033\JAVA_CAB10\tools.zip with 7-zip
• Execute the following commands in cmd.exe:
  • cd C:\JDK.rsrc\1033\JAVA_CAB10\tools\
  • for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all .pack files into .jar files)
• Copy all contents of C:\JDK.rsrc\1033\JAVA_CAB10\tools where you want your JDK to be
• Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.

Si vous configurer Surefire avec certaines options, il ne vous sera plus possible de produire des rapports avec JaCoCo (le fichier jacoco.exec dédié à l'agent JaCoCo ne sera plus produit).

Ce poste explique comment résoudre le problème en remplaçant les configurations de Surefire

OHHHHHH ÇA C'EST BON !
