Every time I experiment with a new language, compiler, interpreter, tool, or whatever, and I want to run that from the command line, I would have to go to System and change my PATH variable. However, the box to put the monster string in consists of only a 1-line text box. I frequently find myself having to copy/paste the PATH string into...

In the build file below, the jar target refers to the jar.class.path property for the manifest class-path. The compile target refers to project.class.path There is redundancy here, because jar.class.path and project.class.path are very similar. They must be both updated when libraries are added, which can be a pain if the list of libra...
Does anyone have code to detect duplicate JARs in the classpath? Background: When there are two versions of the same JAR in the classpath, really strange things can happen. This can even happen when using tools like Maven: Change a dependency and build the WAR without cleaning first. Since target/webapp/WEB-INF/lib wasn't cleaned, the d...

We have some legacy java applications with many class folders and redundant jars on the classpath. One vendor even ships updates via an "overrides" jar that we must prepend to the classpath. Although clean-up ought to be a medium-term goal, I'm wondering if there are any tools out there that will collapse all these directories/jars int...

I am currently setting the classpath to explicitly include those jars however it seems to still pick up the jre first. What I am looking for i...

I have an executable jar that has one class file with a wrong value. I requested that file from the author and corrected the value. Now I want to compile it and add the compiled class file into the jar and run it.

I can see in the Java Build Path config dialog that it can be maniuplated, but I can't think of a good use case for it. If I m...
