UnsolvedSymbolException if passed parameter is a list of two or more elements #3183Description
I'm using Javaparser 3.18.0.
The file to parse src/test/resources/MyClass.java:
import java.io.IOException;
import java.nio.file.Files;
import java.util.Arrays;
class MyClass {
public void writeFile() throws IOException {
Files.write(null, Arrays.asList("", ""));
}
}The parser (in Kotlin):
package my.package
import com.github.javaparser.ParserConfiguration
import com.github.javaparser.ast.body.ClassOrInterfaceDeclaration
import com.github.javaparser.ast.expr.MethodCallExpr
import com.github.javaparser.symbolsolver.JavaSymbolSolver
import com.github.javaparser.symbolsolver.resolution.typesolvers.ReflectionTypeSolver
import com.github.javaparser.utils.SourceRoot
import java.nio.file.Path
fun main() {
val symbolSolver = JavaSymbolSolver(ReflectionTypeSolver())
val sourceRoot = SourceRoot(
Path.of("src/test/resources/"),
ParserConfiguration().setSymbolResolver(symbolSolver)
)
val compilationUnit = sourceRoot.tryToParse()
.single()
.result.get()
val methodCall = (compilationUnit.childNodes[3] as ClassOrInterfaceDeclaration)
.methods.single().body.get()
.childNodes.single()
.childNodes.single() as MethodCallExpr
methodCall.resolve()
}In the attempt to resolve the method call it fails:
Exception in thread "main" UnsolvedSymbolException{context='null', name='We are unable to find the method declaration corresponding to Files.write(null, Arrays.asList("", ""))', cause='null'}
at com.github.javaparser.symbolsolver.JavaSymbolSolver.resolveDeclaration(JavaSymbolSolver.java:167)
at com.github.javaparser.ast.expr.MethodCallExpr.resolve(MethodCallExpr.java:313)
at my.package.MainKt.main(Main.kt:28)
at my.package.MainKt.main(Main.kt)
But if in parsed file list consists of a single element:
Files.write(null, Arrays.asList("", "")); -> Files.write(null, Arrays.asList(""));
it is solved correctly.
