GRefresher

Gradle plugin inspired by sbt-revolver. It provides re-run task which improves development turnaround by recompiling and restarting program in single click.

Key features:

• Recompile and restart by single keypress
• Recompile and restart on source changes

Requirements

---

Gradle 1.12+ (tested on 1.12, but may be supported by earlier versions), Java 1.7+

Getting Started

---

To get started you should add following snippet to your build.gradle

Release:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'ru.shadam.grefresher:grefresher:0.2'
    }
}

Snapshot:

buildscript {
    repositories {
        // .. your preferred repos: mavenCentral() or jcenter() or some else (at least one is required for plugin's dependencies)
        maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }
    }

    dependencies {
        classpath 'ru.shadam.grefresher:grefresher:0.3-SNAPSHOT'
    }
}

apply plugin: 'ru.shadam.grefresher'

Configuration

---

GRefresher provides grefresher extension to configure task

grefresher {
    debug = (true | false) /* Enables debug */
    debugSuspend = (true | false) /* Specifies if application waits for debugger on start */
    debugPort = Integer /* Specifies port for listening to debugger */

    mainClassName = String /* Main class name of your app goes here */
    jvmArgs = [] /* list of jvm args to provide to JVM which will run your app */
    systemProperties = [:] /* map of systemProperties. Each entry expands to following jvm arg: -D${key}=${value} */

    scanInterval = Integer /* Source scanning period. 0 or null to disable scanning */
}

grefresher's Issues

Output of the process gets lost

When I run some app via re-run, there's not standard output/error.

Gradle 2.11.

java.lang.ArrayStoreException for jvmArgs or systemProperties

When running with re-run and jvmArgs or systemProperties are specified.

def configFile = "foo.conf"
jvmArgs = ["-Dconfig.file=${configFile}"]
// or
systemProperties = ["config.file": configFile]

I get this error:

The main class doesn't get started

When I run via plain run it's fine, with re-run the app doesn't get started at all. Output from ./gradlew -info :myProject:re-run:
