Standalone IDE Dependency issue with build scripts

I am attempting to create a small language based off the Calculator example to learn how to create a Standalone IDE and build scripts.  I am new to MPS.

I keep getting the following error in my build script and I can't figure out how to resolve the dependency.  I am hoping someone here can help me.

Here is the entire build script:

build ProjectDecaf generates build.xml 

base directory: ../../ [JComponent javax.swing.JButton[,513,48,20x20,alignmentX=0.0,alignmentY=0.5,border=com.intellij.ide.ui.laf.intellij.WinIntelliJButtonBorder@11227dea,flags=296,maximumSize=,minimumSize=,preferredSize=java.awt.Dimension[width=20,height=20],defaultIcon=,disabledIcon=,disabledSelectedIcon=,margin=com.intellij.util.ui.JBInsets$JBInsetsUIResource[top=2,left=14,bottom=2,right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=...,defaultCapable=true] ]
