Usage

This recipe has no required configuration parameters and comes from a rewrite core library. It can be activated directly without adding any dependencies.

Gradle

1. Add the following to your build.gradle file:

build.gradle

plugins {
    id("org.openrewrite.rewrite") version("7.6.1")
}

rewrite {
    activeRecipe("org.openrewrite.FindDeserializationErrors")
    setExportDatatables(true)
}

repositories {
    mavenCentral()
}

2. Run gradle rewriteRun to run the recipe.

Gradle init script

1. Create a file named init.gradle in the root of your project.

init.gradle

    dependencies {
        rewrite("org.openrewrite:rewrite-java")
    }
    rewrite {
        activeRecipe("org.openrewrite.FindDeserializationErrors")
        setExportDatatables(true)
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
            }

Data Tables

DeserializationErrorTable

Deserialization errors

org.openrewrite.table.DeserializationErrorTable

Table collecting any LST deserialization errors.

Column Name	Description
Source path	The source that failed to be deserialized.
Error message	The error message of the exception that produced the error.
Stack trace	The stack trace of the error.
Language	Language of source file in case it requires a newer CLI version for the ingestion.
Minimum CLI version required by language	Minimum CLI version required to be able to successfully ingest sources of this language.
Actual CLI version used for ingestion	Actual CLI version used to ingest this source.
Timestamp (epoch millis)	UTC timestamp describing when the LST was produced, in milliseconds since the unix epoch.
Timestamp	UTC timestamp describing when the LST was produced, in ISO-8601 format. e.g.: "2023‐08‐07T22:24:06+00:00 UTC+00:00"

SourcesFileResults

Source files that had results

org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

Column Name	Description
Source path before the run	The source path of the file before the run. null when a source file was created during the run.
Source path after the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changes	In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changes	The specific recipe that made a change.
Estimated time saving	An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
