com.sun.tools.javac.jvm.ClassReader$BadClassFile: bad class file when using j4ts

[tinca]

Hi,

I try to get an answer to this issue:
cincheo/jsweet#491

My gradle build file contains:

buildscript {
...
    dependencies {
        classpath('org.jsweet:jsweet-gradle-plugin:2.2.0-SNAPSHOT') { //
            transitive = true }
    }
}
...
dependencies {
    compile group: 'org.jsweet', name: 'jsweet-core', version:'6-SNAPSHOT'
    compile group: 'org.jsweet', name: 'jsweet-transpiler', version:'2.2.0-SNAPSHOT'
    compile group: 'org.jsweet.candies.ext', name: 'angular', version:'1.4.0-SNAPSHOT'
    compile group: 'org.jsweet.candies.ext', name: 'angular-route', version:'1.2.0-SNAPSHOT'
    compile group: 'org.jsweet.candies.trusted', name: 'es6-promise', version:'0.0.0-SNAPSHOT'
    compile 'org.jheaps:jheaps:0.9'
    compile group: 'org.jsweet', name: 'j4ts', version:'0.5.0'
}

However j4ts pom.xml defines jsweet 2.0.0. I tried to change that to 2.2.0 in a fork, but that gives a lot of errors.
I tried to change jsweet (and plugin) to 2.0.0 to no avail.
It seems j4ts is not in sync with current jsweet.

I am keen in testing jsweet on a real project e.g. transpiling JGraphT and if that is successful my project that builds on that, too.

Thanks!

Hello, please use 2.2.0-SNAPSHOT and j4ts 0.6.0-SNAPSHOT and post here if it's better or worse.

Hi,

Thank you for looking into it!
This is what I get:

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':jsweet'.

Could not resolve all files for configuration ':compileClasspath'.

I am using these repos:

maven { url "http://repository.jsweet.org/artifactory/libs-release-local" }
maven { url "http://repository.jsweet.org/artifactory/libs-snapshot-local" }

Can't seem to find in the snapshot repo by using a browser, although the http status code is not a simple missing (404) resource.

[lgrignon]

Can you find the jar in the UI at http://repository.jsweet.org/artifactory/
? Maybe it has never been deployed before.
If you find it, please clean your local maven repo, otherwise you can clone j4ts + deploy

[tinca]

Search for j4ts-0.5.0*.jar finds 2 artifacts in realese and snapshot local repos.
Nothing is returned for j4ts-0.6.0*.jar.

Here is what I get during build attempts.

1. changes to pom:

• jsweet.transpiler.version -> 2.2.0
• jsweet-core -> 5-SNAPSHOT
• jsweet-maven-plugin -> 2.0.0
  Build is OK, No test failure
  Among logged lines there is something that may be worth noting:

2. as 1, but with

3. as 1, but with

So I may try the artifact of the first one. How can I do that?

[tinca]

Any advice how to resolve this?

[schaumb]

The first if it's OK, then it is OK.

this means the rt.jar is in the classpath, but It is OK, this not leading any problem in runtime.

The second:
"
jsweet-maven-plugin -> 2.2.0
org.apache.maven.plugin.MojoFailureException: transpilation failed with 18 error(s)
Build fails.
"
I fixed it locally these errors, but not pull-requested yet. These issues will fix after the change-over (2.2.0) has done.

The third:
"
jsweet-core -> 6-SNAPSHOT
Build fails.
"
I think I fixed these locally too. I will make a PR for this one either.

Any advice how to resolve this?

Hi Bela,
For the first: this message also appeared when I tried to transpile JGraphT and do not remember if the build itself failed or not. Now repeated, message is there, but build seems to be fine, so can try the next steps.
Thanks for the other two too!

Hello @tinca
Did you solve your issue? Sorry we did not answer

[tinca]

In lack of time I left my experiments unfinished. I hope to revive them in the near future, so I wish the necessary packages will all be available and smoothly work together at that time.

[lgrignon]

I hope J4TS will be available for JSweet 3 / Java 11 at that time, but it will require contributors or more time for us (maintainers) so 🤞
:)
