openrewrite Maven plugin configuration

1goal

1.1mvn rewrite:run

1.1.1Run the configured recipes and apply the changes locally.

1.2mvn rewrite:runNoFork

1.2.1运行run命令但不改变maven 的life cycle，因此更方便用于多个maven goal 一起运行

1.3mvn rewrite:dryRun

1.3.1不修改原文件，而是在target/rewrite目录下生成一个diff格式的 rewrite.patch 文件

1.4mvn rewrite:dryRunNoFork

1.4.1运行dryRun命令但不改变maven 的life cycle,因此更方便用于多个maven goal 一起运行

1.5mvn rewrite:discover

1.5.1列出所有recipe，注意style也是一种recipe

2-D 参数

2.1-D 参数比配置文件优先级高，即-D会替换配置文件内的配置

2.1.1-Drewrite.activeRecipes=org.example.R1, org.example.R2

2.1.2-Drewrite.activeStyles=org.example.Style

2.1.3-Drewrite.recipeArtifactCoordinates=org.example:your-recipe:1.0

指定recipe 对应的maven artifact

3Plugin configuration

3.1activeRecipes

3.2activeStyles

3.2.1代码风格

3.3checkstyleDetectionEnabled

3.3.1默认会侦测maven Checkstyle plugin 并使用对应style

xml 复制代码

<artifactId>maven-checkstyle-plugin</artifactId>
				<version>3.3.1</version>

					<execution>
						<id>verify-style</id>

				</executions>

3.4configLocation

3.4.1rewrite.yml 文件所在目录

3.5dependencies

3.5.1依赖 artificial，一般用于非官方recipes

3.6failOnDryRunResults

3.6.1DryRun发现内容需要修改时候返回fail

3.6.2默认false，不返回

3.7exclusions

3.7.1排除内容

3.8plainTextMasks

3.8.1指出那些文件为plaintext格式

3.8.2默认内容

3.9pomCacheDirectory

3.9.1pom.xml文件cache目录

3.9.2默认为 ~/.rewrite-cache

3.10pomCacheEnabled

3.10.1default is true

3.11sizeThresholdMb

3.11.1非java 资源被忽略分析的上限大小

3.11.2The default threshold is 10Mb.

3.12skipMavenParsing

3.12.1跳过pom文件分析，默认为false

3.13 exportDatatables

3.13.1 export the data tables generated by the active recipes.

3.13.2The default is false.

3.13.3The resulting files can be found in the directory <build directory>/reports/rewrite/datatables/<timestamp>.

files

org.openrewrite.table.RecipeRunStats.csv
org.openrewrite.table.SourcesFileResults.csv

注意在运行目录下，使用maven cli的时候要注意不一定在修改的project 目录下

3.13.4 核心代码
