Formatter2 xtend classes not converted to java on Linux [message #1801251]

Hi all,

I have the following added to my mwe2:

formatter = {
  generateStub = true  
  generateXtendStub = true
}

I have 3 java classes and 2 xtend classes in the formatting2 package found under src.

When I run MWE2 workflow, I see the 2 xtend classes generated as java under xtend-gen folder formatting2 package.

This only happens on Windows while on Linux it doesn't generate the 2 java classes under xtend-gen. I can't figure out what's going on.

I am using Xtext 2.15.0.

Which files do you get
Are you sure this is not a case insensitive problem
Can you share a minimal example

formatting2 package has the following:
- DSLFormatterPreferenceKeys.java
- DSLFormatterPreferenceValuesProvider.java
- DSLFormattingUtils.java
- DSLFormatter.xtend
- DSLGenericFormatter.xtend

On windows xtend-gen formatting2 package contains:
- DSLFormatter.java
- DSLGenericFormatter.java

On Linux xtend-gen formatting2 package contains nothing.
No errors are shown during generation.

Can it be a permissions issue?
Case sensitivity, but how?

Note:
If in eclipse I open any of the xtend files and write anything then save the java file appears in xtend-gen folder.

Please share a reproducible example. Try the same with a hello world project

Besides that you can debug around TextFileAccess

I am not able to reproduce it on some small project.

I'll take a look at TextFileAccess and let you know. Thanks

I was able to do it on DomainModel example.
Steps:
1. Create new xtext project using domain model project
2. Remove org.eclipse.xtext.example.domainmodel/src-gen/* and org.eclipse.xtext.example.domainmodel/xtend-gen/
3. Run the build command:

R:/jdk1.8.0_181_64/bin/javaw.exe -Xmx768m -Dfile.encoding=Cp1252 -classpath "D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext_2.15.0.v20180916-0722.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.ecore.xmi_2.12.0.v20160420-0247.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.ecore_2.12.0.v20160420-0247.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.common_2.12.0.v20160420-0247.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.antlr.runtime_3.2.0.v201101311130.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\com.google.inject_3.0.0.v201605172100.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe.core_1.3.20.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.apache.commons.cli_1.2.0.v201404270220.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe2.runtime_2.9.0.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe.utils_1.3.20.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext.util_2.15.0.v20180916-0722.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\com.google.guava_15.0.0.v201403281430.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\javax.inject_1.0.0.v20091030.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext.xbase_2.15.0.v20180916-1104.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext.common.types_2.15.0.v20180916-1104.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtend.lib_2.15.0.v20180916-1130.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext.xbase.lib_2.15.0.v20180916-1130.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtend.lib.macro_2.15.0.v20180916-1130.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.equinox.common_3.8.0.v20160509-1230.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.objectweb.asm_6.2.1.v20180823-1831.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.xtext.xtext.generator_2.15.0.v20180916-0722.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.codegen.ecore_2.12.0.v20160526-0356.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.codegen_2.11.0.v20160526-0356.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe2.launch_2.9.0.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe2.language_2.9.0.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.eclipse.emf.mwe2.lib_2.9.0.v201605261103.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.apache.commons.logging_1.2.0.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\org.apache.log4j_1.2.15.v201012070815.jar;D:\eclipse.platform.4.6.3\eclipse.xtext2.15.0\plugins\com.ibm.icu_56.1.0.v201601250100.jar;D:\eclipseWorkspace\org.eclipse.xtext.example.domainmodel\bin" org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher src/org/eclipse/xtext/example/domainmodel/GenerateDomainmodel.mwe2

4. You will find that xtend-gen contains nothing

Using eclipse build workspace creates the .java files under xtend-gen as expected. But the build command doesn't.

i dont understand you. if you dont call the xtend generator xtend will not be generated. this is intended.
you need to call xtend-maven-plugin / gradle / ant / java to compile the xtend files to java

I thought generate mwe2 includes the compilation of xtend files.

I am trying to figure out how to call the xtend compiler at the moment.

It keeps giving me errors because it can't find the Java classes.

Java compiler can't proceed due to failing to bind classes that are xtend.
Xtend compiler can't proceed due to not finding .class files generated by Java compiler.

the xtend compiler does compile the java classes under the hood so it is working.
do you use maven or gradle?
or pure java?

org.eclipse.xtend.core.compiler.batch.Main

I used ant called java with the Main you mentioned "org.eclipse.xtend.core.compiler.batch.Main".

My issue is that the -cp is too long..

Okay I got it to work now. This was helpful http://xtextcasts.org/episodes/12-building-with-ant?autoplay=true

hmmm have no idea on that.
what do you have on that path?
maybe copy all dependencies to a single dir with a short path
