Parameters accepted as nested elements

<classpath> ...

This object represents a path as used by CLASSPATH or PATH environment variable.

    <pathelement location="/path/to/file.jar" />
    <pathelement path="/path/to/file2.jar:/path/to/class2;/path/to/class3" />
    <pathelement location="/path/to/file3.jar" />
    <pathelement location="/path/to/file4.jar" />

The object implemention sometask must provide a method called createSomepath which returns an instance of Path. Nested path definitions are handled by the Path object and must be labeled pathelement.

The path element takes a parameter path which will be parsed and split into single elements. It will usually be used to define a path from an environment variable.

Attribute Description Type Required
refid Makes this instance in effect a reference to another Path instance.

You must not set another attribute or nest elements inside this element if you make it a reference.

Reference ?
path Parses a path definition and creates single PathElements. String ?
