* Tests stopped compiling after preview RPC was embedded,
because compileOnly dependencies are not visible to tests;
* Local test runs were broken, because the default
compose.version (1.0.0-alpha4-build328) is not compatible
with Kotlin 1.5.31 (compose.version is always overridden on CI,
so CI runs work);
The build `0.4.0-build182` upgrades
`kotlinx-collections-immutable` library
(which is used by the compose runtime) to 0.3.4,
which was published to maven central,
so most usages of sunsetting jcenter repo
can be removed now.
Resolves#557
There are two versions used in the Gradle plugin:
* The version of the plugin itself;
* The version of Compose dependency used by the plugin.
On CI both versions are set to the same value specific to the build.
However, locally using 0.1.0-SNAPSHOT for the Compose version is inconvenient,
because we don't publish 0.1.0-SNAPSHOT anywhere.
Even if it existed, a moving version is not convenient for using in tests.
This commit changes version handling:
* The version of Compose is set via `compose.version` Gradle property
to the latest stable version, unless overridden by
`COMPOSE_GRADLE_PLUGIN_COMPOSE_VERSION` env. var.
* The version of the plugin is set via `deploy.version`
Gradle property to 0.1.0-SNAPSHOT,
unless overridden by `COMPOSE_GRADLE_PLUGIN_VERSION` env. var
