Error with Visual Studio 17.3.1

[Philippe-Laval]

The nuget package antlr4buildtasks 10.7.0 has a warning icon in Visual Studio.
I got this error message

C:\Users\philippe.laval.nuget\packages\antlr4buildtasks\10.7.0\build\Antlr4BuildTasks.targets(133,3): error ANT02: The Antlr4 tool failed.

I managed to solve the problem : I added JavaExec in the project and/or changed JAVA_HOME to C:\Program Files\Java\jdk-18.0.2.1

<ItemGroup>
	<Antlr4 Include="Modeler.g4">
		<Package>Modeler</Package>
		<JavaExec>c:/Program Files/Java/jdk-18.0.2.1/bin/java.exe</JavaExec>
	</Antlr4>
</ItemGroup>

<ItemGroup>
	<PackageReference Include="Antlr4.Runtime.Standard" Version="4.10.1" />
	<PackageReference Include="Antlr4BuildTasks" Version="10.7.0" />
</ItemGroup>

Long overdue, I'm setting up a bunch of tests to methodically go through all the possible permutations of java versions, JAVA_HOME, JAVA_EXEC, PATH, etc., and make sure each strange condition is handled with good information outputted. But, I do see that if you try to use an ancient java (jdk v7(), it crashes without any real information just as you encountered. Thanks for the info.

Added in a version check, will release in 11.0 of Antlr4BuildTasks. d212f0f

Thanks for adding more tests and a better error output.
Effectively on my main computer I had SDK 11 and 17 installed. On the other computer SDK 8 or 9 => I had the problem.
For my friend, which reported the error to me, he solved also the problem by installing JDK 18.
