I found this article: https://android.jlelse.eu/yet-another-awesome-kotlin-feature-parcelize-5439718ba220 - and I wanted to look at the code there, https://github.com/burakeregar/KotlinParcelize.
I am using Ubuntu 18.04, and I thought of running ./gradlew
in terminal.
My Android SDK dir is in, say, /path/to/adt-bundle-linux-x86-20140321/sdk
...
So, I did:
$ cd /tmp
$ git clone https://github.com/burakeregar/KotlinParcelize.git KotlinParcelize_git

$ cd KotlinParcelize_git/
$ ./gradlew assembleDebug

Ok, so I run /path/to/adt-bundle-linux-x86-20140321/sdk/tools/android
, install Build-Tools 26.0.2 (apparently the minimum version for the gradle version in the repo, and those build tools I did not have before), try again:

If you run ./gradlew assembleDebug --debug
, you get a massive log of some 6400+ lines, which I pasted here: KotlinParcelize_gradlew_debug.log, the only relevant part seems to be:

... but I still cannot understand - what plugin is in "Wrong plugin option format"?
Well, I'm stuck here .... How can I get this example to compile?
EDIT: few things I found:
e: Wrong plugin option format: null, should be plugin:<pluginId>:<optionName>=<value>
is apparently a message fromkotlinc
(I guess, the kotlin compiler), as noted in KT-41303: CLI: "wrong plugin option format: null, should be plugin::=" with compiler plugins- So, it would have been nice to see when and how
./gradlew
callskotlinc
- however, not even--debug
does not output such a command line, because "That's not possible. Simply, because most of the Gradle tasks do not invoke CLI commands." ( How can I view the CLI command executed by a Gradle task in Android Studio? ) - I tried importing this in Android Studio 4.0.1, and at a certain time, I got the message Unsupported Modules Detected: Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project ; then I deleted
.idea
folder, reimported again - did not get that message anymore, but still same plugin null error - Bit more digging in the debug log, it can be determined that the
compileDebugKotlin
step is the one failing, which can be triggered with./gradlew :app:compileDebugKotlin --info
- but still the same error.
