Hello @luxiangyuan

When I uncomment “to enable …” and “jvmArgs…” line in Elektron-SDK1.2.2.java.rrg\Java\Ema\Examples\build.gradle file as shown below:

tasks.withType ( JavaExec ) { 
	to enable the logger comment out the line below 
	jvmArgs += "-Djava.util.logging.config.file=../Core/src/main/resources/logging.properties" 
}

Then, I get the same problem as you

The reason is “to enable …” line is not the code that gradlew can run. It is the real comment.

After I change build.gandle file to comment “to enable …” line as shown below:

tasks.withType ( JavaExec ) { 
	//to enable the logger comment out the line below 
	jvmArgs += "-Djava.util.logging.config.file=../Core/src/main/resources/logging.properties" 
}

Then I can run gradlew Ema:Examples:tasks -all successfully:

Hope this help.
