* Improve gradle plugin task parsing Added _gradle and _gradlew as symbolic links to gradle.plugin.zsh, otherwise the plugin was not properly loaded. Output from `gradlew tasks --all` is now parsed in two levels, first we find segments between `------...` and a newline. Second, all those lines are parsed and cleaned using awk and added to .gradletasknamecache. Tested on gradle 2.13, and gradlew 2.14. * Remove .gradletasknamecache before regenerating it Remove the .gradletasknamecache file to avoid having an unnecessary newline at the top of the file when regenerating it. * Improve gradle task parsing by writing .gradletasknamecache atomically Previously the .gradletasknamecache file was written line by line inside a parsing loop, which could cause errors such as half-written cache files if the process was aborted. This also removes the need of deleting the .gradletasknamecache file before parsing.
