플레이 프레임 워크 : oracle을위한 데이터베이스 진화 활성화

Question

재생 프레임 워크에 bug이 있습니다. 이 버그에 따르면 play_evolutions은 Oracle 데이터베이스를 인스턴스화 할 수 없습니다. 수동 play_evolutions 테이블 생성하기 위해 나는 다음과 같은 스크립트를 사용하고 this question에서 언급 한 바와 같이 :

수동으로 테이블을 생성와

CREATE TABLE play_evolutions 
(
    id Number(10,0) Not Null Enable, 
    hash VARCHAR2(255 Byte), 
    applied_at Timestamp Not Null, 
    apply_script clob, 
    revert_script clob, 
    state Varchar2(255), 
    last_problem clob, 
    CONSTRAINT play_evolutions_pk PRIMARY KEY (id) 
); 

, 진화가 적용됩니다,하지만 프로그램은 다음과 같은 스택 추적과 정지이의
