Plugin fails to run.

[kec2]

I can't get your plugin to work

Gradle version 3.4
Java 7 64bit
Windows 7 64Bit

Build.gradle

plugins {
  id "com.github.sherter.google-java-format" version "0.6"
}

apply plugin: 'java'

sourceCompatibility = 1.7
targetCompatibility = 1.7

javadoc.options.encoding = 'UTF-8'
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

repositories {
    mavenCentral()
}

This is the gradle error:

[sherter]

I don't have access to a windows 7 machine right now, but I'll increase the priority of issue #10 on my TODO list (I couldn't reproduce the problem on Linux, OpenJDK 7, Gradle 3.4)

[sherter]

I re-tried on windows 7, but couldn't reproduce the problem:

I also tried with Java 8 and didn't have any problems.
Could you provide more details? Does it always produce this error?

PS: I don't understand why I have to create an Oracle account in order to download Java 7... ugh!

[kec2]

I can't reproduce this problem today. I have tried two projects (one of which failed last week) and it works fine.

[mcs6502]

I had the same failure with google-java-format-gradle-plugin version 0.6 on Win10 with jdk8. The "String index out of range" at GoogleJavaFormatExtension.groovy:32 could occur if your projects don't share the same parent directory. This can happen, for example, if you are using dependency substitution in your Gradle project, and replacing some of your modules with projects that reside in a parent directory outside your current project. For me the workaround was to avoid using dependency substitution in my build.gradle while running this plugin's tasks.

[mcs6502]

The expression at GoogleJavaFormatExtension.groovy:32 "p.buildDir.path.substring(project.projectDir.path ..." may produce unexpected results if one project is not nested within another. This could happen, for example, due to Gradle dependency substitution, if you replace a module with a project in a parent directory.
For me the workaround was to temporarily stop using dependency substitution in my build.gradle while I was running this plugin.

[sherter]

@mcs6502 Thanks for the detailed analysis (and sorry for the delay). I've never used dependency substitution before. Do you have an example project at hand?

[cdennison]

Same issue here - I get the same String index out of range error when defining a Gradle dependency in a separate folder.

This didn't work:

build.gradle
dependencies {
    compile project(":common")
    ...
}

settings.gradle
include ':common'
project(':common').projectDir = new File('../common')

The fix was to comment out the projectDir which isn't great because now it won't build so I have to comment, verify, uncomment, build.

settings.gradle
include ':common'
//project(':common').projectDir = new File('../common')

[DwordPtr]

I'm experiencing this issue today on macOS.
