eclipse.ini变量 [英] eclipse.ini variables

问题描述

eclipse.ini或eclipse命令行可以进行变量解析吗？

如$ PATH或$ {java.home}？

解决方案

如常见问题：如何我运行Eclipse？

如果在eclipse / jre目录下可用，Eclipse JRE将被使用;否则启动器将参考系统路径变量。 Eclipse不会查询JAVA_HOME环境变量。

eclipse命令行可以使用环境变量（像任何其他命令）：

  eclipse -vm $ jAVA_HOME / bin 
  

将工作。

但Eclipse本身（或eclipse.ini）将不会直接使用解析环境变量。

只有这样一个 eclipse.ini使用完整的路径。

其实， bug 102239 已经要求这种功能...自2005年以来！

Bug 102239 - [launcher] < launcher> .ini / eclipse.ini

$ b $中的环境变量替换b

如果启动器支持插入，这将是非常有帮助的< launcher> .ini 中的环境变量。

无论什么形式都有意义（例如， @ENV ，％ENV％， $ {ENV} ， $ {env_var：ENV} ）

eg像

  -vm 
 $ {MYRCPAPP_VM} 
 -mx $ {MYRCPAPP_HEAPSIZE} 
  

但答案请求帮助：

启动器是用C编写的。代码在平台启动程序项目中。

这在任何参数，包括vm，vmargs等，在这种情况下，这将需要发生在本机代码。

does eclipse.ini or eclipse command line does variable parsing?

such as $PATH or ${java.home} ?

解决方案

As mentioned in FAQ: How do I run Eclipse?

If available under the eclipse/jre directory, the Eclipse JRE will be used; otherwise the launcher will consult the system path variable. Eclipse will NOT consult the JAVA_HOME environment variable.

a eclipse command line can use environment variable (like any other command):

eclipse -vm $jAVA_HOME/bin

would work.

But Eclipse itself (or eclipse.ini) will not use parse directly an environment variable.
A eclipse.ini like this one only use full paths.

Actually, bug 102239 is already asking for that kind of feature... since 2005!

Bug 102239 - [launcher] Environment variable substitution in <launcher>.ini/eclipse.ini

It'd be very helpful if the launcher would support the insertion of environment variables in the <launcher>.ini.
Whatever form might make sense (e.g. @ENV, %ENV%, ${ENV}, ${env_var:ENV})

e.g. something like

-vm
${MYRCPAPP_VM}
-mx${MYRCPAPP_HEAPSIZE}

But the answers ask for help on this:

The launcher is written in C. The code is in the platform-launcher project.

[To] want this on any argument including the vm, vmargs etc, in which case this would need to happen in the native code.
