Error: Could not find or load main class

[ionox0]

Command used:

./cwlexec /home/johnsoni/Innovation-Pipeline/workflows/QC/qc_workflow_wo_waltz.cwl ~/Innovation-Pipeline/test/workflows/EZ_QC_test.yaml
Error: Could not find or load main class com.ibm.spectrumcomputing.cwl.Application

I've downloaded and extracted the 0.2.2 release, is there any advice on this error?

Also was able to start the 0.2.0 version, but ran into this error:

./cwlexec /home/johnsoni/Innovation-Pipeline/workflows/QC/qc_workflow_wo_waltz.cwl ~/Innovation-Pipeline/test/workflows/EZ_QC_test.yaml
The field [SchemaType] is required by [type].

This was addressed here: https://github.com/IBMSpectrumComputing/cwlexec/issues/32

@ionox0 Are you able to run any simple CWL description with v0.2.2?

You could also try packing your CWL into a single file with cwltool --pack /home/johnsoni/Innovation-Pipeline/workflows/QC/qc_workflow_wo_waltz.cwl > qc_workflow_wo_waltz-packed.cwl. This does $import and $include processing, so that may be easier for cwlexec to ingest until they become more compliant with the entirety of CWL v1.0.

@ionox0, do you set the CWL_EXEC_HOME environment variable? I think you may need to check it, or would you try the below commands, this will print the cwlexec version

CWL_EXEC_HOME=<your cwlexec uncompressed path>
CWL_EXEC_LIBS_PATH="$CWL_EXEC_HOME/libs"
CWL_EXEC_JAR_LIBS=`find $CWL_EXEC_LIBS_PATH -type f | awk '{printf("%s:", $1)}'`
CWL_EXEC_MAIN_CLASS="com.ibm.spectrumcomputing.cwl.Application"

java -classpath $CWL_EXEC_JAR_LIBS $CWL_EXEC_MAIN_CLASS -v

@mr-c Yes I believe the issue may be due to $import and $include statements. Will get back when I return to this and test with a more standard workflow, thank you!
