# Purpose: Install a jar file and create all the given symlinks to it.

# Example:

# oe_jarinstall foo-1.3.jar foo.jar

# Installs foo-1.3.jar and creates symlink foo.jar.

# oe_jarinstall -s foo-1.3.jar foo.jar

# Installs foo-1.3.jar to staging and creates symlink foo.jar.

# oe_jarinstall -r foo-1.3.jar foo_1_3.jar foo.jar

# Installs foo_1_3.jar as foo-1.3.jar and creates a symlink to this.

# where the ".jar" has been omitted. The string is stored in the script

# variable whose name is given in the first argument to this function.

# Stores ${datadir_java}/foo.jar:${datadir_java}/baz.jar:${datadir_java}/bar.jar

# Stores ${STAGING_DATADIR_JAVA}/foo.jar:${STAGING_DATADIR_JAVA}/baz.jar:${STAGING_DATADIR_JAVA}/bar.jar

# in variable "bootcp".

# Provide the -s at the beginning otherwise strange things happen.

# If -s is given the function checks whether the requested jar file exists

# and exits with an error message if it cannot be found.

# Note: In order to encourage usage of the DEPENDS variable, the function

# can accept recipe names. If a recipe has no corresponding Jar file it

# is ignored. Be careful with recipes where the recipe name is different

# from the the Jar file name!
