I have installed the new release of Java Card Platform Development Kit, according to the following guide. This includes all the prerequisites, as well as version 3.0.5u2 of JCDK. As a heads up, I tried installing this on 2 different computers (one has Win7, the other Win10) and reinstalled everything on both.
The problem I'm encountering is that none of the sample projects will build properly. When I try to build the HelloWorld sample, for example, I get the following text printed in the build console:

Missing file containing component hashes.

where options include:
-help Print this message and exit.
-o <filename> Output filename. default: stdout
-version Print version number and exit.
-nobanner Do not print banner.
-nobeginend Suppress "CAP_BEGIN", "CAP_END" APDU commands.
-package <pkgname> Package name.
While the regular console has this to say:
Executing "$JC_CLASSIC_HOME\bin/converter.bat" -debug -nobanner -out CAP JCA -classdir "$JC_CLASSIC_HOME\samples\classic_applets\HelloWorld\applet\bin" -d "$JC_CLASSIC_HOME\samples\classic_applets\HelloWorld\applet\deliverables" -exportpath "$JC_CLASSIC_HOME\api_export_files" -applet 0xA0:0x00:0x00:0x00:0x62:0x03:0x01:0x0C:0x01:0x01 com.sun.jcclassic.samples.helloworld.HelloWorld com.sun.jcclassic.samples.helloworld 0xA0:0x00:0x00:0x00:0x62:0x03:0x01:0x0C:0x01 1.0

Now, I'm not 100% sure, but I think that when I had version 3.0.5u1 installed, I was able to build the sample projects.
It seems the build process of the Java Card Classic Development Kit 3.0.5u2 (jcdk) Eclipse Plugin is broken. During the build of an java card applet, three scripts located in the bin subdirectory of the jcdk installation directory are executed (if using default applet settings in eclipse):
- converter.bat generating the export file *.exp
- converter.bat generating cap (and jca) file
- scriptgen.bat generating the script files for installing the applet to a java card.
The problem is, that scriptgen requires a hashfile containing hashes for the applet components. You can see this if you decompile the class com.sun.javacard.scriptgen.Main of tools.jar in jcdk lib folder.
This hashfile is not generated during the eclipse build process, neither is the scriptgen script called with the corresponding program option "-hashfile <hash-file>". The only workaround currently is using the jcdk tools on the console manually. Therefor you can use the output of console in eclipse and adopt it for your needs.
Example output for a simple test applet:

(Note: you have to add the path to the jcdk export files used by the applet, these you can find out by activating verbose output in the java card package settings and searching the console output for referenced exp files.)
Then at lease you can generate the install script with the command:
G:\eclipse_javacard\workspace\TestJCDKApplet>E:\eclipse-oxygen-64bit\JCDKit_305u2\bin/scriptgen.bat -package test.jcdk.applet -o
G:\eclipse_javacard\workspace\TestJCDKApplet\apdu_scripts/cap-test.jcdk.applet.script G:\eclipse_javacard\workspace\TestJCDKApplet\deliverables/test/jcdk/applet/javacard/applet.cap -hashfile applet.hash
