picocli-annotation-processing-tests fail on Java 16+ #1939
Description
Related to #1930
Annotation tests fail on Java 16+ with this error:
java.lang.IllegalAccessError: class com.google.testing.compile.Parser (in unnamed module @0xc267ef4) cannot access class com.sun.tools.javac.util.Context (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.util to unnamed module
The build.gradle for that module had the below workaround for this, but this no longer seems to work...
tasks.withType(Test.class) {
if (org.gradle.api.JavaVersion.current().isJava12Compatible()) { // only a problem from Java 16, but okay
// https://github.com/google/compile-testing/issues/222
it.jvmArgs '--add-opens=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED'
}
}
google/compile-testing#222 (comment) suggests fixing the tests to avoid some methods and do String comparison instead of relying on functionality that depends on the internal compiler.
E.g. in java/picocli/annotation/processing/tests/Issue769Test.java, the following change fixes the issue:
// assertThat(compilation)
// .generatedFile(StandardLocation.SOURCE_OUTPUT, "generated/picocli/issue769/MyMixin.java")
// .hasSourceEquivalentTo(JavaFileObjects.forResource("generated/picocli/issue769/MyMixin.java"));
String generated1 = compilation.generatedFile(StandardLocation.SOURCE_OUTPUT, "generated/picocli/issue769/MyMixin.java").get().getCharContent(false).toString();
String expected1 = JavaFileObjects.forResource("generated/picocli/issue769/MyMixin.java").getCharContent(false).toString();
assertEquals(expected1.replaceAll("\\r?\\n", "\n"), generated1.replaceAll("\\r?\\n", "\n"));
// assertThat(compilation)
// .generatedFile(StandardLocation.SOURCE_OUTPUT, "generated/picocli/issue769/SubCommand.java")
// .hasSourceEquivalentTo(JavaFileObjects.forResource("generated/picocli/issue769/SubCommand.java"));
String generatedSub = compilation.generatedFile(StandardLocation.SOURCE_OUTPUT, "generated/picocli/issue769/SubCommand.java").get().getCharContent(false).toString();
String expectedSub = JavaFileObjects.forResource("generated/picocli/issue769/SubCommand.java").getCharContent(false).toString();
assertEquals(expectedSub.replaceAll("\\r?\\n", "\n"), generatedSub.replaceAll("\\r?\\n", "\n"));
