Subject [jira] Created: (ETCH-69) Compiler throws URISyntaxException if there are spaces in the classpath

Compiler throws URISyntaxException if there are spaces in the classpath
-----------------------------------------------------------------------

                 Key: ETCH-69
                 URL: https://issues.apache.org/jira/browse/ETCH-69
             Project: Etch
          Issue Type: Bug
          Components: compiler
    Affects Versions: 1.0.2
         Environment: Windows XP, java 1.6, maven 2.0.9, ant 1.7.0
            Reporter: Brian Smith
            Priority: Minor


While trying to write a maven POM that executes the etch task via the antrun plugin, I discovered
EtchCompiler throwing an exception if the path to the etch jars contains spaces. This resulted
from my M2 repository being located in c:\Documents and Settings\brian\.m2\repository. The
output is:

The documentation for URL.toURI() says that it cannot produce a URI if the URL is not RFC
2396 compliant. Using a multi-arg constructor for URI fixes the problem. In EtchCompiler.java,
replace line 222 with:
                    String scheme = "file";
                    int pathBegin = scheme.length() + 1;
                    String path = s.substring(pathBegin);
                    // multi-arg constructor properly escapes paths
                    File f = new File(new URI(scheme, null, path, null));
