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

我的团队使用eclipse概要文件XML文件中定义的代码格式约定，该文件如下所示：

<?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"/>
...

只有当

${JAVA\u FORMATTER\u CONFIG\u FILE}

是一个eclipse首选项文件，其文件名为

org.eclipse.jdt.core.prefs

且内容为：

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

如何以编程方式获取

.prefs

文件，而无需从eclipse UI手动导入XML概要文件？

从eclipse Oxygen workbench

• 导出当前首选项：文件->导出->首选项
• 选择“Java代码样式首选项”
• 选择名称和目标并保存（似乎必须使用.epf扩展名）

该文件将包含（除其他外）自定义fomatter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...
...

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。

使用XSLT、正则表达式或从XML中读取ID/值对并将其保存到属性文件，可以轻松地将XML文件转换为属性文件：

=>

${ID}=${value}

。或者我误解了您的问题，而不是将格式化程序配置文件XML转换为

.settings/org.eclipse.jdt.core.prefs

？我明白了。我不确定XML是否有任何特殊处理或映射到.pref值。我真的在寻找一种以编程方式实现这一点的方法。但是，假设上游XML文件从未更改，或者我不必处理多个XML，那么我想您是对的，这只能执行一次，并且.prefs或.epf文件可以共享。如果上游XML规范发生变化，那么我想我会在评论中使用霍尔格的建议。下面是以编程方式导出/导入的和。
