The problem looks to be related to this line: compiler = COMPILER.getDeclaredConstructor(IBackend.class).newInstance(backend);
It's looking for a constructor on MXMLJSC (not to be confused with MxmlJSC) that takes an IBackend as a parameter. There is no longer a constructor like that in 0.8.0. If I understand the dual changes correctly, MXMLJSC now automatically creates an IBackend based on the -targets value. It looks like this code does indeed still need changes to support dual. - Josh On Wed, Jul 5, 2017 at 3:09 PM, Josh Tynjala <joshtynj...@gmail.com> wrote: > I'm trying to create a new FlexJS 0.8.0 project in IntelliJ IDEA, and I'm > getting the following output when I try to build the project: > > Information:[HelloIDEA]: Starting Flex compiler: > "/Applications/IntelliJ IDEA.app/Contents/jdk/Contents/Home/jre/bin/java" > -Dapplication.home=/Users/joshtynjala/Development/Flex/sdks/flexjs-0.8.0 > -Dfile.encoding=UTF-8 -Djava.awt.headless=true -Duser.language=en > -Duser.region=en -Xmx512m -classpath "/Applications/IntelliJ > IDEA.app/Contents/plugins/flex/lib/idea-flex-compiler-fix.jar:/Applications/IntelliJ > IDEA.app/Contents/plugins/flex/lib/flex-compiler.jar:/ > Users/joshtynjala/Development/Flex/sdks/flexjs-0.8.0/lib/flex-compiler-oem.jar" > com.intellij.flex.compiler.FlexCompiler 54900 > Information:[HelloIDEA]: mxmlc -load-config=/Users/ > joshtynjala/Library/Caches/IntelliJIdea2017.1/compile- > server/helloidea_6d5abd99/_temp_/IntelliJ_IDEA/idea-B028A5AE-12E86E20.xml > -load-config+=/Users/joshtynjala/Development/Flex/ > sdks/flexjs-0.8.0/ide/IDEA/intellij-config.xml > Information:[HelloIDEA]: unknown error > Information:[HelloIDEA]: at java.lang.Class.getConstructor0(Class.java: > 3082) > Information:[HelloIDEA]: at java.lang.Class.getDeclaredConstructor(Class. > java:2178) > Information:[HelloIDEA]: at flex2.tools.MxmlJSC. > getCompilerInstance(MxmlJSC.java:48) > Information:[HelloIDEA]: at flex2.tools.MxmlJSC.execute(MxmlJSC.java:89) > Information:[HelloIDEA]: at flex2.tools.Tool.compile(Tool.java:68) > Information:[HelloIDEA]: at flex2.tools.Mxmlc.mxmlc(Mxmlc.java:73) > Information:[HelloIDEA]: at com.intellij.flex.compiler. > flex4.Flex4Handler.compileSwf(Flex4Handler.java:81) > Information:[HelloIDEA]: at com.intellij.flex.compiler. > CompilationThread.run(CompilationThread.java:48) > Information:[HelloIDEA]: Compilation failed > Information:7/5/17, 2:56 PM - Compilation completed with 1 error and 0 > warnings in 595ms > Error:[HelloIDEA]: java.lang.NoSuchMethodException: > org.apache.flex.compiler.clients.MXMLJSC.<init>(org. > apache.flex.compiler.driver.IBackend) > > I followed the steps in these instructions that worked correctly with > 0.7.0: > > https://cwiki.apache.org/confluence/display/FLEX/Using+ > FlexJS+with+IntelliJ+IDEA > > I'm not very familiar with this part of the code, but it looks to me like > the call to MxmlJSC.getCompilerInstance() can't find IBackend?
