syntax error in built json

[Deleted user]

I've been trying to get the source for this project to compile. After installing the correct version of java and maven I can run ./build.js which finishes successfully, but when I run test/simple.js or try:

> require('./compile.js')({ jsCode: [{src: 'const x = 1 + 2;'}] })

I get this error:

The file that closure-compiler-js is attempting to parse appears to be: closure-compiler/target/classes/com/google/javascript/jscomp/resources.json:

 node closure-compiler/target/classes/com/google/javascript/jscomp/resources.json
module.js:561
    throw err;
    ^

SyntaxError: /home/substack/projects/closure-compiler-js/closure-compiler/target/classes/com/google/javascript/jscomp/resources.json: Unexpected token : in JSON at position 1077462

The other json file from which this file is derived doesn't appear to have the same issue:

$ node closure-compiler/src/com/google/javascript/jscomp/resources.json && echo $?
0

There may still be a problem if you try to build the JS version from the GWT/Java source. The code that's deployed to NPM is fixed.

@MatrixFrog knows more.

This should have been fixed by google/closure-compiler@f21c592 -- can you check if you're synced past that commit?

[Deleted user]

I don't have that commit. What branch is that in?

[MatrixFrog]

It's on master, but it's in the main closure-compiler repo rather than this one. So you probably need to do something like:

git submodule init
git submodule update
cd closure-compiler
git pull

to get the submodule updated. My knowledge of git submodules is iffy, @samthor can probably help if that's not quite right. Then cd back to this repo:

cd ..

and build:

./build.js

Thanks, this fixed it.
