@SneakyThrows当使用lombok“@SneakyThrows”时，不支持class文件大版本61

Question

I am learning to use Lombok in a Maven project. When I use "@SneakyThrows", there are some errors. I found that when I deleted "@SneakyThrows", the errors disappeared.

Here are the errors and code.

 java: Error during the transformation of 'com.zem.mybatis.DAO.BO.Bus'; post-compiler 'lombok.bytecode.SneakyThrowsRemover' caused an exception: java.lang.IllegalArgumentException: Unsupported class file major version 61 at org.objectweb.asm.ClassReader.<init>(ClassReader.java:189) at org.objectweb.asm.ClassReader.<init>(ClassReader.java:170) at org.objectweb.asm.ClassReader.<init>(ClassReader.java:156) at lombok.bytecode.AsmUtil.fixJSRInlining(AsmUtil.java:37) at lombok.bytecode.SneakyThrowsRemover.applyTransformations(SneakyThrowsRemover.java:46) at lombok.core.PostCompiler.applyTransformations(PostCompiler.java:43) at lombok.core.PostCompiler$1.close(PostCompiler.java:77) at jdk.compiler/com.sun.tools.javac.jvm.ClassWriter.writeClass(ClassWriter.java:1508) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.genCode(JavaCompiler.java:738) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.generate(JavaCompiler.java:1617) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.generate(JavaCompiler.java:1585) at jdk.compiler/com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:946) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.lambda$doCall$0(JavacTaskImpl.java:104) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.invocationHelper(JavacTaskImpl.java:152) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.doCall(JavacTaskImpl.java:100) at jdk.compiler/com.sun.tools.javac.api.JavacTaskImpl.call(JavacTaskImpl.java:94) at org.jetbrains.jps.javac.JavacMain.compile(JavacMain.java:238) at org.jetbrains.jps.incremental.java.JavaBuilder.lambda$compileJava$2(JavaBuilder.java:518) at org.jetbrains.jps.incremental.java.JavaBuilder.invokeJavac(JavaBuilder.java:564) at org.jetbrains.jps.incremental.java.JavaBuilder.compileJava(JavaBuilder.java:516) at org.jetbrains.jps.incremental.java.JavaBuilder.compile(JavaBuilder.java:359) at org.jetbrains.jps.incremental.java.JavaBuilder.doBuild(JavaBuilder.java:284) at org.jetbrains.jps.incremental.java.JavaBuilder.build(JavaBuilder.java:238) at org.jetbrains.jps.incremental.IncProjectBuilder.runModuleLevelBuilders(IncProjectBuilder.java:1507) at org.jetbrains.jps.incremental.IncProjectBuilder.runBuildersForChunk(IncProjectBuilder.java:1141) at org.jetbrains.jps.incremental.IncProjectBuilder.buildTargetsChunk(IncProjectBuilder.java:1288) at org.jetbrains.jps.incremental.IncProjectBuilder.buildChunkIfAffected(IncProjectBuilder.java:1106) at org.jetbrains.jps.incremental.IncProjectBuilder.buildChunks(IncProjectBuilder.java:877) at org.jetbrains.jps.incremental.IncProjectBuilder.runBuild(IncProjectBuilder.java:459) at org.jetbrains.jps.incremental.IncProjectBuilder.build(IncProjectBuilder.java:197) at org.jetbrains.jps.cmdline.BuildRunner.runBuild(BuildRunner.java:131) at org.jetbrains.jps.cmdline.BuildSession.runBuild(BuildSession.java:334) at org.jetbrains.jps.cmdline.BuildSession.run(BuildSession.java:162) at org.jetbrains.jps.cmdline.BuildMain$MyMessageHandler.lambda$channelRead0$0(BuildMain.java:218) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635)

 @AllArgsConstructor @Data @Builder public class Bus { private @Singular("a") List<Integer> arrayList; @Getter(lazy = true) private final static Bus bus = Bus.builder().a(1).build(); }

This is the dependency of Lombok.

You're using Lombok 1.18.16, but Lombok added Java 17 support in version 1.18.22 (see its changelog , or issue 2898 ). You need to update to 1.18.22 or higher to make it work on Java 17.
