Re: [jdt-core-dev] ClasspathEntry.getPath() returns wrong absolute paths

Hi Alexander,

I believe this is working as intended.
Please refer to org.eclipse.jdt.core.JavaCore.newLibraryEntry(...)
for more details.

Regards,
Jay

ClasspathEntry.getPath() returns wrong absolute        paths
for simple jars

Hi all,

I want to collect all classpath entries that my java project
uses. For that I'm using

IClasspathEntry [] cpe = javaProject.getResolvedClasspath(false);
for (int i=0; i<cpe.length; i++) {
if (IClasspathEntry.CPE_LIBRARY == cpe[i].getEntryKind())
result.add(cpe[i].getPath().toOSString());
}
}

The javadoc of ClasspathEntry says that

• A binary library in the current project, in another project, or in the external file system. In this case the entry identifies a JAR (or root folder) containing package fragments and .class files. The classpath entry must specify the absolute path to the JAR (or root folder), and in case it refers to an external JAR, then there is no associated resource in the workbench. Entries of this kind are associated with the CPE_LIBRARY constant.

However
for a most simple library that I've added to .classpath as follows

<classpathentry kind="lib" path="lib/mylib.jar"
/>

the getPath() returns "/myproject/lib/mylib.jar"
where myproject is my project's name. Moreover isAbsolute() method of this
path returns true. However that is wrong because this path is really relative
to my workspace's root.

On the other hand the JDK's jars (like rt.jar) are being
returned correclty with a fully absolute path.

Is this the expected behavior? If no, should I report
it in bugzilla? If it is expected behavior then what is the correct way
to collect all jars with "real" absolute paths?_______________________________________________
