java - Eclipse - Setting .classpath file for existing project -

-

I have a Java project I'm working from another project of Eklips (this is a propono symphonic project I think).

In my eclipse I created a new Java project and asked it to use the existing code. It seems that it has brought in all code.

However, after loading the project, I get this error: 

  Project 'My Project' is missing the required Java project: 'Weka 3-7'

There is one with these materials in it. The slashpath file is: 

  & lt ;? Xml version = "1.0" encoding = "UTF-8" & gt; & Lt; Classpath & gt; & Lt; Classpathentry kind = "src" path = "src" /> & Lt; Classpathentry kind = "con" path = "org.eclipse.jdt.launching.JRE_CONTAINER" /> & Lt; Classpathentry combineaccessrules = "false" type = "src" path = "/ wca-3-7" /> & Lt; Classpathentry kind = "Output" path = "bin" /> & Lt; / Classpath & gt;

What have I tried so far:

I have established Vaika 3-7 and then I have to say the following. Updated slashpath file and reloaded the project. 

  & lt ;? XML version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Classpath & gt; & Lt; Classpathentry kind = "src" path = "src" /> & Lt; Classpathentry kind = "con" path = "org.eclipse.jdt.launching.JRE_CONTAINER" /> & Lt; Classpathentry combineaccessrules = "false" type = "src" path = "c | / program files / waka-3-7" /> & Lt; Classpathentry kind = "Output" path = "bin" /> & Lt; / Classpath & gt;

But now I get an error message: 

  The required source folder in Project 'My Project' is missing: 'c. / Program Files / Wake-3 -7 '

Please help me get trapped.

You want to use context menu: My project :: (right mouse click) :: build Path: Configure the Build Path. It gives you the option of adding / removing projects, jars, source folders, etc., which you need to provide those project references that your project reference. You can do manually get the same effect by hacking .classpath , but you have to know very to know what you are doing Always use frontend, unless it is absolutely necessary for you.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
