Would you please provide an script to switch java.

[liaoya]

I like scoop and your java bucket. It has a little inconvenience that

• It always add bin to PATH so that there will be multi java in path even first one will win
• It will reset JAVA_HOME when the new java installed

I will switch to different java frequently. It's perfect if

• Do not put bin in PATH when new java installed
• Provide a script to switch java by reset JAVA_HOME, remove old %JAVA_HOME%\bin from PATH and add the new one.

There are two solutions available today, without removing env_add_path from the manifests:

1. scoop reset <java>@<version>
2. Using find-java from extras

scoop reset works very well for the current session, and will also update the user's path.

Globally installed javas takes precedence over user installed javas, so if you have admin rights on your PC, sudo scoop install -g oraclejdk-lts will install a java that is always default for new sessions.

Consider the following:

PS C:> scoop install oraclejdk-lts
Installing 'oraclejdk-lts' (8u172-b11) [64bit]
PS C:> scoop install oraclejdk10
Installing 'oraclejdk10' (10.0.1-10) [64bit]
PS C:> scoop install zulu6
Installing 'zulu6' (6.18.1.5) [64bit]
PS C:> scoop install openjdk10
Installing 'openjdk10' (10.0.1) [64bit]
PS C:> java -version
