Unable to index gradle/gradle repository

[olafurpg]

To reproduce

git clone https://github.com/gradle/gradle.git
cd gradle
lsif-java index
...
[error] * What went wrong:
[error] A problem occurred configuring project ':kotlin-dsl-plugins'.
[error] > Could not create task ':kotlin-dsl-plugins:embeddedIntegTest'.
[error]    > Failed to query the value of task ':kotlin-dsl-plugins:embeddedIntegTest' property 'javaLauncher'.
[error]       > No compatible toolchains found for request filter: {languageVersion=8, vendor=any, implementation=vendor-specific} (auto-detect false, auto-download false)

Looks toolchains related.

It would be really nice to be able to index the Gradle repo since I'm struggling to load the project in IntelliJ 😅
