I'm getting the following when trying to use JPA, spring, noargs, all-open.

Class 'CmcSbsbSubsc' should have [public, protected] no-arg constructor

this doesn't seem to be a compiler issue though...it compiles fine through maven. Does this mean this intention is wrong because we are doing noarg at annotation time? and i should tell IDEA to ignore that warning on the class name?

@Entity
@Table(name = "CMC_SBSB_SUBSC", schema = "FACETCOR")
data class CmcSbsbSubsc(
    @Id
    @Column(name = "SBSB_CK", nullable = false)
    val sbsbCk: Long,

    @Column(name = "SBSB_ID", nullable = false)
    val sbsbId: String
)

Include JPA plugin in your build configuration

@Mikhail yes i have that, maven compiles it fine. but it seems intellij sees it as a problem that i do not have a ctor
[INFO] Applied plugin: 'spring'
[INFO] Applied plugin: 'jpa'
[INFO] Applied plugin: 'all-open'
[INFO] Applied plugin: 'lombok'

hm
Try restarting / File -> Repair IDE ?

It will compile in any case, but would fail at runtime if your JPA entity is not proper

@sreich Don't use data class, just plain class instead. Seems to work much better

[Mikhail]

I use data on my JPA entities and override hashcode and equals . Works fine.

@Mikhail you didn't happen to use querydsl did you? trying to get annotation processing happening, with maven here

[sreich]

got it working 🙂
