Question

我尝试使用code formatter docs在命令行上运行eclipse java格式化程序，但它失败并显示

的异常消息

<current working directory>/--launcher.library file does not exist.

看看code formatter application code，似乎正在发生的事情是，某些eclipse参数被格式化程序的命令行解析器解释为相对文件名，而这些文件名并不存在。

我知道some people used to be able to get this to work，但这是5年多前使用旧版本的eclipse，我想知道是否有人能够在eclipse中使用相同的功能4.4

更新1：

这是我使用的命令行：

/home/alexq/eclipse-luna-SR2-4.4.2/eclipse/eclipse -nosplash -consolelog -debug -application org.eclipse.jdt.core.JavaCodeFormatter -verbose -config /home/alexq/eclipse-user-files/formatter-config-for-scripts/MyCodingStandards.ini /home/alexq/eclipse-4.4.2-workspaces/MyWorkspace/MyProject/src/com/example/myproject/MyClassToBeFormatted.java

以下是我的eclipse.ini文件的内容：

-showlocation

Answer 1

作为一种解决方法，我从here下载eclipse 3.6并尝试运行相同的eclipse formatter命令，并且它成功了。

Answer 2

另一个解决方法 - 使用Eclipse Neon.2，我刚刚从eclipse.ini的开头删除了-showlocation，现在该文件如下所示：

-startup
plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.401.v20161122-1740
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
-XX:+UseG1GC
-XX:+UseStringDeduplication
-Dosgi.requiredJavaVersion=1.8
-Xms2048m
-Xmx2048m

JavaCodeFormatter现在可以从命令行运行。

使用eclipse 4.4在命令行上运行Eclipse Java格式化程序
