+Gradle Debian Helper
+--------------------
+
+This project contains helper tools to ease the packaging of Gradle based projects in Debian.
+It consists in:
+ * a Gradle plugin resolving the dependencies against the system Maven repository (/usr/share/maven-repo).
+ The resolver uses the same Maven rule files that maven-debian-helper and maven-repo-helper employ
+ (debian/maven.rules, debian/maven.ignoreRules).
+ * a build listener displaying a message periodically to prevent the builders from killing Gradle on slow architectures.
+ * a debhelper class detecting Gradle build files, initializing the plugin and running Gradle in offline mode.
+
+
+Usage
+-----
+
+1. Add a build dependency on gradle-debian-helper in debian/control
+
+2. Use a debian/rules file with:
+
+ %:
+ dh $@ --buildsystem=gradle
+
+3. Create debian/maven.rules and/or debian.maven.ignoreRules with the dependency rules
+
+4. For building only some subprojects and ignoring the other,
+ pass Gradle parameters to dh_auto_build:
+
+ override_dh_auto_build:
+ dh_auto_build -- :project1:jar :project2:jar
+
+
+Limitations
+-----------
+
+* Dependencies with a version range are not handled (e.g. org.foo:bar:1.0+)
+* Transitive dependencies with a non generic version (neither 'debian' nor '.x')
+ must be added to debian/maven.rules in order to preserve the version
+ (with a rule like: org.foo bar * * * *)
