addEnvHooks "$targetOffset" addPkgToClassPath
Add a setup hook that automatically sets up $CLASSPATH All JARs in $pkg/share/java (for each $pkg in the build inputs) are added to $CLASSPATH. Thus, you can say buildInputs = [ setJavaClassPath someJavaDependency ]; and the JARs in someJavaDependency will be found automatically by tools like javac or ant. Note that the manual used to say that JARs should be installed in lib/java; this is now share/java, following the Debian policy: http://www.debian.org/doc/packaging-manuals/java-policy/x110.html The directory share/java makes more sense because JARs are architecture-independent. (Also, a quick grep shows that we were not exactly consistent about this in Nixpkgs.) 2014-01-06 12:42:37 +00:00			`# This setup hook adds every JAR in the share/java subdirectories of`

treewide: Don't use envHook anymore This commits needs a MAJOR audit as I oftentimes just guessed which of `$hostOffset`, `$targetOffset`, or a fixed offset should be used. 2017-08-10 23:22:07 +01:00			`addEnvHooks "$targetOffset" addPkgToClassPath`
