e8182c17ad chore(release): 1.0.0-dev.1 [skip ci]
# 1.0.0-dev.1 (2022-03-23)

### Bug Fixes

* avoid ignoring test resources (fixes [#1](https://github.com/ReVancedTeam/revanced-patcher/issues/1)) ([d5a3c76](d5a3c76389))
* current must be calculated after increment ([5f12bab](5f12bab5df))
* **gradle:** publish source and javadocs ([87bbde5](87bbde5e06))
* **Io:** fix finding classes by name ([460d62a](460d62a24c))
* **Io:** JAR loading and saving ([#8](https://github.com/ReVancedTeam/revanced-patcher/issues/8)) ([4d98cbc](4d98cbc9e8))
* nullable signature members ([#10](https://github.com/ReVancedTeam/revanced-patcher/issues/10)) ([8db8893](8db8893ab1))
* Patch should have access to the Cache ([6c0f082](6c0f0823c9))
* remove broken code ([0e72a6e](0e72a6e85f))
* set index for insertAt to 0 by default ([1769132](1769132a9e))
* workflow on dev branch ([7e67daf](7e67daf878))

### Code Refactoring

* convert Patch to abstract class ([23e897a](23e897a7a9))
* Optimize Signature class ([#11](https://github.com/ReVancedTeam/revanced-patcher/issues/11)) ([49beec9](49beec9fc6))
* Rename `net.revanced` to `app.revanced` ([3ab42a9](3ab42a932c))

### Features

* Add `findParentMethod` utility method ([#4](https://github.com/ReVancedTeam/revanced-patcher/issues/4)) ([00c6ab7](00c6ab7faf))

### BREAKING CHANGES

* Array<Int> was changed to IntArray. This breaks existing patches.
* Package name was changed from "net.revanced" to "app.revanced"
* Method signature of execute() was changed to include the cache, this will break existing implementations of the Patch class.
* Patch class is now an abstract class. You must implement it. You can use anonymous implements, like done in the tests.

# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
