使用Maven Mojo sql的错误:执行
TL; DR版本:我希望能够使用Maven Mojo SQL插件通过mvn
命令行随意创建/删除我的数据库模式中的任何给定表(或者为这些表加载数据)。 怎么样?
我是一位长期的Java开发人员,但大部分时间我都生活在一个基于ant
的世界。 我喜欢ant
的力量和明确性,以及它给我的一切控制。 然而,在我的新工作中,有一个推动使用maven
。 所以我决定使用我在家工作的一个项目来学习它。
一,我已经成立了一个不同的个人项目的事情是完全建立和拆除我的Postgres数据库的能力ant
在命令行上。 我可以单独或一致地对我喜欢的任何表格,序列和集成测试数据进行切片和切片。 当然,这意味着我有一个gajillion ant
目标,但它工作得很好。 我喜欢这个; 多年来它一直很好。
在研究如何在周末的Maven中实现这一点时,我找到了Mojo SQL Maven插件。 在查看使用页面(我使用这个术语松散地,因为它实际上只是一个没有解释的半示例)和示例页面之后,我能够对我的pom.xml
文件进行一些更改。 我在示例(postgressql)中修复了一些明显的拼写错误,并引用了PostgreSQL JDBC页面以确保我的JDBC连接字符串正确。 我将粘贴下面的所有pom.xml
(修改为保护有罪):

现在,由于我还没有创建数据库,因此它不会显示在PG命令行的l
:
[mike@mike myapp]$ psql template1
Welcome to psql 8.3.5, the PostgreSQL interactive terminal.
Type: copyright for distribution terms
h for help with SQL commands
? for help with psql commands
g or terminate with semicolon to execute query
q to quit
template1=# l
List of databases
Name | Owner | Encoding
-----------+----------+----------
postgres | postgres | UTF8
template0 | postgres | UTF8
template1 | postgres | UTF8
(3 rows)
因此,当我运行mvn sql:execute
,我期望我的数据库被创建......或者至少不会在drop-db-before-test-if-any
任务上失败,因为它被设置为在错误时继续。 但是当然:
[mike@mike myapp]$ mvn sql:execute

在最后一行提到的错误页面没有帮助; 它只是告诉我,一个插件导致了错误,而不是Maven本身。
所以让我们用-X
开关运行它。 我只会发布错误的有趣部分:

但是,但是,... <onError>continue</onError>
!
所以,对于这些问题:
create-person.sql
文件。 我从例子中知道,我可以在那里有多个文件,比如create-address.sql
。 但是在ant
,只要我遵守参照完整性的顺序来执行蚂蚁任务,我就能够独立于person
表创建address
表。 maven
有可能这样吗? 如果是这样,怎么样? 抱歉的详细程度,并提前感谢您的任何帮助。
无法执行目标org.codehaus.mojo:sql-maven-plugin:1.5:execute (default-cli)
default-cli
是插件从命令行调用时的特殊executionId
。 看到这个。
你已经将所有的sql插件执行绑定到maven生命周期阶段,但是你试图直接调用插件。
mvn test
应该可以工作。
这是一个相关的SO讨论。
