使用checkstyle（默认）配置，预提交中的lineLength为100？

Question

背景

当我运行以下预提交配置时：

- repo: https://github.com/gherynos/pre-commit-java
    rev: v0.2.9 # Use the ref you want to point at
    hooks:
      - id: pmd
        # args: ["--cache"]
        # exclude: /test/
      - id: cpd
        # exclude: /test/
      - id: checkstyle
        # Set the path to your Checkstyle configuration file
        # args: ["-c", "checkstyle.xml"]
        # exclude: /test/

checkstyle 抛出 32 个各种类型的警告，包括

InvalidJavadocPosition

。这正如预期的那样。但是，默认情况下它使用 80 个字符的 lineLength，而 google_style_java 使用 100 个字符。我想更改 checkstyle 以使用 100 个字符，我通过添加一个

checkstyle.xml

文件来实现，其内容为：

<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
        "-//Checkstyle//DTD Checkstyle Configuration 1.3//EN"
        "https://checkstyle.org/dtds/configuration_1_3.dtd">

<module name="Checker">
    <!-- Configure the line length check with a maximum limit of 80 characters -->
    <module name="LineLength">
        <property name="max" value="80"/>
    </module>
</module>

并启用：

args: ["-c", "checkstyle.xml"]

。

问题

但是，后一种配置使 checkstyle only 检查 lineLength。为了解决这个问题，我可以创建一个自定义 checkstyle 配置，其中包含 checkstyle 支持的所有检查。然而，这是相当耗费人力的，更重要的是，如果 checkstyle 更新，它需要我手动更新配置。因此，我想“只使用默认的检查样式设置，因为预提交使用它”，但行长度应该是 100 而不是 80。

问题

因此，我想问，如何使用预提交使用的默认 checkstyle 配置，除了 100（而不是 80）的行长度检查

通过在

中包含其他检查找到了解决方案，例如：
