Hi,
I had the same kind of issue when trying to run Team -> Share Project.
I hit following message :
"Unsupported encoding ISO-8859-1 for the 'odataBasic.".settings":org.eclipse.jdt.core.prefs' file; only UTF-8 encoding is supported. Apply the quick fix to change the encoding settings."
I tried the environment variable. It was not enough to fix the issue.
Then I changed the encoding of the file mentioned in the error message with iconv utility.
( I used the iconv utility of cygwin. )
d://hana_studio_repository/odaBasic/.settings 23# iconv -t utf8 org.eclipse.jdt.core.prefs
eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
org.eclipse.jdt.core.compiler.compliance=1.8
org.eclipse.jdt.core.compiler.problem.assertIdentifier=error
org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
org.eclipse.jdt.core.compiler.source=1.8
This fixed the issue, I was able to run "Team -> Share Project" afterwards.
