GroovyParsingException when parsing Gradle build file

[BrendanHart]

What version of OpenRewrite are you using?

I am using

• OpenRewrite v8.45.0
• Gradle plugin v7.1.4
• rewrite-groovy v8.45.0
• rewrite-gradle v8.45.0
• Gradle 6.9

How are you running OpenRewrite?

I am using the Gradle plugin, with an init script.

What is the smallest, simplest way to reproduce the problem?

I have simplified my original build.gradle to something which produces a similar exception. I have been unable to reproduce this in a unit test since they use Groovy 3, which doesn't seem to produce the exception. I have tried to create a unit test with Groovy 2 dependencies, but it seemed the GroovyParserVisitor then sees a ClassNotFoundException for LamdaExpression, so I'm unsure how to configure a test to compile the Groovy code with Groovy 2 yet have Groovy 3 classes available. The only way I have been able to reproduce is by actually running gradle --init-script init.gradle rewriteDryRun.

init.gradle

initscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2" }
    }
    dependencies { classpath("org.openrewrite:plugin:latest.release") }
}
rootProject {
    plugins.apply(org.openrewrite.gradle.RewritePlugin)
    dependencies {
        rewrite("org.openrewrite:rewrite-java")
    }
    rewrite {
        activeRecipe("org.openrewrite.groovy.format.AutoFormat")
        setExportDatatables(true)
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
            }
        }
    }
}

build.gradle

def x = (1 / 1 ) * 100
System.out.println("test")

What did you expect to see?

No fail to parse errors.

What did you see instead?

Failed to parse error.

What is the full stack trace of any errors you encountered?

Are you interested in contributing a fix to OpenRewrite?

[timtebeek]

Any improvement with the latest releases? There were fixes specifically for the Groovy parser:
https://github.com/openrewrite/rewrite/releases

[BrendanHart]

Thanks for the suggestion, but just tried 8.46.1 and unfortunately still seeing the same error (8.47.0 doesn't seem available in maven central yet).

[greg-at-moderne]

I've just tried reproducing by creating these two files in an empty directory and running ~/git/openrewrite/rewrite/gradlew --init-script init.gradle rewriteDryRun and it worked.

Also adding the two lines:

def x = (1 / 1 ) * 100
System.out.println("test")

in a unit test for GroovyParser also passes.

So I think there might be a bit more of a nuance to pinpoint the actual issue here.

[BrendanHart]

Hi @greg-at-moderne, thanks for trying, did you use Gradle 6.9 also?

[greg-at-moderne]

Ah. No. I didn't. I've used 8.12. Maybe that's the thing.

[greg-at-moderne]

When I try
gradle-6.9/bin/gradle --init-script init.gradle rewriteDryRun
using JDK 11 I get a successful build (with JDK 17 it wouldn't work):

➜  g1 sdk use java 11.0.25-amzn

Hi @greg-at-moderne,

In your logs I see "there were problems parsing build.gradle", I think if you run your build with --info it will show the stack trace I seen

[greg-at-moderne]

And you are right indeed!
I get a slightly different exception:

Caused by: java.lang.StringIndexOutOfBoundsException: begin 51, end 51, length 50
        at java.base/java.lang.String.checkBoundsBeginEnd(String.java:3319)

        at org.openrewrite.groovy.GroovyParserVisitor$RewriteGroovyVisitor.insideParentheses(GroovyParserVisitor.java:660)

But it looks too similar to yours for it to be an accident.

Thanks!

[BrendanHart]

Just some extra info - I just tried with Java 11, and then the stack trace looks like yours, I was previously using Java 8.

[shanman190]

So it's probably the parentheses. Gradle 6.x I believe uses Groovy 2.5 while Gradle 7.x uses Groovy 3.x. One of the features that comes with Groovy 3.x is better recording of parentheses depth which rewrite-groovy takes advantage of when it's available, but has to fallback to trying to guess the parentheses depth on these older versions.

[BrendanHart]

When I was previously debugging this, I did notice that when using Gradle 8, the parentheses level of the * node was 0, whereas in Gradle 6 it was 1. I think the parentColumn and childColumn differed in determineParenthesisLevel. Not sure if this is helpful but it aligns with what you have suggested @shanman190 .
