Google’s Closure Compiler, which I’ve used for many years, seems to be down (https://closure-compiler.appspot.com/home).

Googling turned up a lot of conflicting data, some of which seems to imply it’s no longer available online, and you have to run it locally. However, none of the download links I tried worked.

Anyone know the current status of the Google Closure Compiler?

  • It's back online now, but the service is deprecated (the project itself is not), so if you depend on it you might want to self-host. If you look up "closure compiler online" in your favorite search engine you'll find a few alternative hosted services, usually ad-supported. – redburn Oct 17 '22 at 12:11

All the information is available in the official docs. Indeed both the UI and the API are deprecated. You should download the Java application for local use.

See Getting Started with the Closure Compiler Application:

Download the most recently released JAR file from the Maven repository, and save it in closure-compiler.

Now the Maven web UI is indeed far from obvious, but here's how it goes:

  1. In the big table, under the Version heading, click the version you want. At the time of writing, that's v20220803, released on 9 August. (That also answers your question about the current status; new releases are still happening.)
  2. In the table at the top, next to Files, click the link named "jar" to start your download.

  • Downloaded latest jar, but when I ran it, I got this error message: Exception in thread "main" java.lang.UnsupportedClassVersionError: com/google/javascript/jscomp/CommandLineRunner has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 But when I run java -version, it makes no mention of class file versions, only the overall version of the JRE: Java HotSpot(TM) Client VM (build 25.341-b10, mixed mode, sharing) How do I get the correct class version? – aksarben Aug 13 '22 at 22:33
  • Upgrade you Java 8 to [at least version 11](https://stackoverflow.com/questions/9170832/list-of-java-class-file-format-major-version-numbers). – Thomas Aug 14 '22 at 07:17
  • Yup, right you are. Until I saw your note, I didn’t know there was a Java version past 8, which is what I got from Oracle last time an auto-update occurred. Looks like the the JDK and accompanying JRE are many versions beyond the consumer JRE, which is evidently still at 8. – aksarben Aug 15 '22 at 21:59
  • I think it's because of license changes: "Java 8 LTS last free software public update for commercial use was released by Oracle in March 2022, while Oracle continues to release no-cost public Java 8 updates for development[3] and personal use indefinitely." https://en.wikipedia.org/wiki/Java_version_history Since they don't know if you're using it commercially, it won't auto-update to a version where that is no longer allowed. – Thomas Aug 16 '22 at 06:30

It's down for me since this morning also. Nothing on their @googledevs Twitter account and no status updates that I can locate
