以编程方式将 Eclipse 格式化程序配置文件 XML 导出到 .prefs

Programmatically export eclipse formatter profile XML into .prefs

我的团队使用在 eclipse 配置文件 XML 文件中定义的代码格式约定,看起来像这样:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<profiles version="12">
<profile kind="CodeFormatterProfile" name="This Team's Formatting Convention"  version="12">
<setting id="org.eclipse.jdt.core.formatter.insert_space_after_ellipsis" value="insert"/>
...

我将 eclipse 用作命令行格式化程序,使用如下命令:

eclipse -nosplash -application org.eclipse.jdt.core.JavaCodeFormatter \
    -config ${JAVA_FORMATTER_CONFIG_FILE} ${*}

这仅在 ${JAVA_FORMATTER_CONFIG_FILE} 是文件名类似于 org.eclipse.jdt.core.prefs 且内容为:

的 eclipse 首选项文件时有效
eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
org.eclipse.jdt.core.compiler.compliance=1.8
org.eclipse.jdt.core.compiler.problem.assertIdentifier=error
org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
org.eclipse.jdt.core.compiler.source=1.8

如何在不从 eclipse UI 手动导入 XML 配置文件的情况下以编程方式获取 .prefs 文件?

来自 Eclipse Oxygen workbench、

  • 导出当前首选项:文件 -> 导出 -> 首选项
  • Select "Java Code Style Preferences"
  • 选择名称和目的地并保存(似乎必须使用 .epf 扩展名)

该文件将包含(除其他外)自定义格式配置

/instance/org.eclipse.jdt.ui/formatter_profile=_my-java-formatter
/instance/org.eclipse.jdt.ui/formatter_settings_version=13
/instance/org.eclipse.jdt.ui/org.eclipse.jdt.ui.formatterprofiles=<?xml version\="1.0" encoding\="UTF-8" standalone\="no"?>\n<profiles version\="13">\n<profile kind\="CodeFormatterProfile" name\="my-java-formatter" version\="13">\n...
...

然后您可以 运行 格式化程序

eclipse -nosplash -application org.eclipse.jdt.core.JavaCodeFormatter -config eclipse-formatter.epf Test.java

输出:

org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.  Will retry after the state location is initialized.
org.eclipse.m2e.logback.configuration: Logback config file: /home/luis/eclipse-workspace/.metadata/.plugins/org.eclipse.m2e.logback.configuration/logback.1.8.3.20180227-2137.xml

首选项导出完成一次,然后您可以共享 eclipse-formatter.epf 文件。 希望对您有所帮助。
