Hello. Which JVM are you using? (Oracle or openjdk or other?) Which version of maven?
I'm using Oracle's Java.
$ java -version java version "1.8.0_171" Java(TM) SE Runtime Environment (build 1.8.0_171-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
$ mvn -version Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T14:49:05-05:00) Maven home: D:\bin\apache-maven-3.5.3\bin.. Java version: 1.8.0_171, vendor: Oracle Corporation Java home: C:\Program Files\Java\jre1.8.0_171 Default locale: en_CA, platform encoding: Cp1252 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
tools.jar which contains the JCTree class should be in the maven classpath. Could you please check that this is true?
Maven has a classpath? I don't see anything in the docs about that (aside from classes included within a pom file). I've not set the general classpath for my computer either. Are you saying I should set the system CLASSPATH? Also, where is this tools.jar that needs to be included?
It should be downloaded to your local maven repository, it is a transitive dependency of the maven plugin. https://github.com/cincheo/jsweet/blob/master/transpiler/pom.xml#L215
Have you tried adding this artifact as a dependency?
I'm not that familiar with maven and am not sure what you're talking about here. I checked the .m2 directory in my home directory, and there was no tools.jar there (although there was a tools-8.pom.lastUpdated file). I added the XML for the tools dependency you linked to above to the projects pom file and compiled again, but am still getting errors.
Here's the log of my build: buildLog.txt
Yeah there should be a jar in .m2\repository\com\sun\tools\8 try forcing refresh your dependencies please
I deleted my .m2\repository and tried again. Still getting the same error. tools.jar is not downloaded for some reason (ie, it's not appearing in the .m2/repository/com/sun/tools/8 directory). I'm attaching a log of my build. buildLog.txt
hi i have the same problem however i see a tools-8.jar in my .m2 yet it is still telling me im missing com/sun/tools/javac/tree/JCTree
Hello, thanks for reporting. Which JVM please? Maybe you have the same version
oh i figured it out so what you have to do is go to environmental variable make a new user variable called JAVA_HOME and set the value to C:\Program Files\Java\jdk1.8.0_171 silly me it builds fine now
I had my JAVA_HOME pointing to my jre. After changing that and checking out a new version of jsweet-quickstart, I was able to compile.
Jsweet doesn't seem to work with the latest Java 10 JDK, though.
Hello, yes JSweet was fully tested for Java 8 but not validated for Java 9 & 10 (I think it breaks with Jigsaw)
Well, thank you for solving the problem on your own, it's a shame that the JRE instead of JDK error is not properly reported to the user (I think there is a warning in the logs, but way too shy :))
Could you please create a specific issue for this? I will enhance it.
Or if you want to PR, contributions are all welcome
I added an issue at https://github.com/cincheo/jsweet/issues/443.
What do you mean by PR?
PR stands for Pull Request :)
I just came across JSweet, and am trying it out to see how it works. Unfortunately, I’m having trouble getting the quick start to run. I got up to step 3 on your Getting Started tutorial (http://www.jsweet.org/getting-started/) and encountered some errors. I’m building this via Powershell on a Windows 10 box.
After downloading a lot of packages from Maven, the compiler spits out the below message. It looks like something called JCTree is missing. Is this supposed to be in the JDK? I have Java 1.8.0_171 installed on my machine.
