Description
I use maven and faced with a problem when had used your plugin.
Short log of problem is
[ERROR] PROTOC FAILED: some/path//SomeClass.java: Tried to insert into file that doesn't exist.
My pom.xml

</plugin>as noticed there, there and there
Using dsl markers relies on protoc insertions, so take care to ensure that the kroto-plus output directory is the same as the directory for generated java code
Then I tried protobuf-gradle-plugin with settings
protobuf {
protoc { artifact = "com.google.protobuf:protoc:${versions.protobuf}" }
generatedFilesBaseDir = "$buildDir/generated-sources"
plugins {
grpc { artifact = "io.grpc:protoc-gen-grpc-java:${versions.grpc}" }
kroto {
artifact = "com.github.marcoferrer.krotoplus:protoc-gen-kroto-plus:${versions.krotoplus}:jvm8@jar"
}
}
generateProtoTasks {
def krotoConfig = file("krotoPlusConfig.asciipb")
all().each { task ->
task.inputs.files krotoConfig
task.plugins {
grpc { outputSubDir = "java" }
kroto {
outputSubDir = "java"
option "ConfigPath=$krotoConfig"
}
}
}
}
}and that worked.
I ran command in debug mode and compare output protobuf-maven-plugin and protobuf-gradle-plugin.
protobuf-gradle-plugin run only one protoc command with pipe of plugins
protoc-3.6.1-linux-x86_64.exe -I/api/src/main/proto -I/api/build/extracted-protos/main -I/api/build/extracted-include-protos/main --java_out=/api/build/generated-sources/main/java --plugin=protoc-gen-grpc=/home/stepan/.gradle/caches/modules-2/files-2.1/io.grpc/protoc-gen-grpc-java/1.16.1/f26e45fd6dc4ebaf6d76b22b290b337ee96aed54/protoc-gen-grpc-java-1.16.1-linux-x86_64.exe --grpc_out=/api/build/generated-sources/main/java --plugin=protoc-gen-kroto=/home/stepan/.gradle/caches/modules-2/files-2.1/com.github.marcoferrer.krotoplus/protoc-gen-kroto-plus/0.2.2-SNAPSHOT/9c02fa688b3c00b1f768fb9302e85205a798fc05/protoc-gen-kroto-plus-0.2.2-SNAPSHOT-jvm8.jar --kroto_out=ConfigPath=/api/krotoPlusConfig.asciipb:/api/build/generated-sources/main/java some_protos.proto ...
--java_out --> --protoc-gen-grpc --> protoc-gen-kroto
protobuf-maven-plugin run protoc commands N executions times
and in my case last command is
protoc-3.6.1-linux-x86_64.exe --proto_path=/api/src/main/proto --proto_path=/api/target/protoc-dependencies/3f38729cce82adb9f25c7327ca2059db --proto_path=/api/target/protoc-dependencies/5f1e9201db2bd80331b59aeb26f3d508 --plugin=protoc-gen-kroto-plus=/api/target/protoc-plugins/protoc-gen-kroto-plus-0.2.2-SNAPSHOT-jvm8.jar --kroto-plus_out=ConfigPath=/api/krotoPlusConfig.asciipb:/api/target/generated-sources/protobuf/java some_protos.proto ...
that lead to build failure.
When I have added --java_out=/api/target/generated-sources/protobuf/java to command above. It worked fine
protoc-3.6.1-linux-x86_64.exe --proto_path=/api/src/main/proto --proto_path=/api/target/protoc-dependencies/3f38729cce82adb9f25c7327ca2059db --proto_path=/api/target/protoc-dependencies/5f1e9201db2bd80331b59aeb26f3d508 --java_out=/api/target/generated-sources/protobuf/java --plugin=protoc-gen-kroto-plus=/api/target/protoc-plugins/protoc-gen-kroto-plus-0.2.2-SNAPSHOT-jvm8.jar --kroto-plus_out=ConfigPath=/api/krotoPlusConfig.asciipb:/api/target/generated-sources/protobuf/java some_protos.proto ...
I don't know which products this bug\behavior belongs to.
