Jove is another name for "Jupiter," the Roman god, so people in Roman times would swear by him. This has carried forward to current times, especially in England. "By God!" was a strong oath promising (usually) to accomplish or complete some action or prevent something, but it was considered too blasphemous to say in "polite company" (especially during times when the (Roman Catholic) church (or Anglican - Church of England) was strong.
Polite company was generally the upper classes. Only upper class children received much formal education, but that almost always included some Latin and Greek. Indeed, much of history was studied in the original languages in which contemporary accounts of Rome and Greece were written. So being aware of the Roman gods the "polite" form of "By Jove" was substituted for the blaspheming oath of "By God". Since the reference was to the discredited notion of Jupiter as a god, it was not blaspheming of the name of the Christian God worshiped in the religion of Britain at the time.
The use of "by Jove" has declined, especially in the last (20th) century, and now, though rarely used, is often an expression of surprise or delight rather than a more formal "oath". In Shakespeare's time the "oath" "By Jove" was still considered a direct enough (though indirect) reference to "God" that it was actually considered a curse (aka, swearing, blaspheming).
All of the above except 'Jove' is a shortened version of Jehova, not Jupiter
"Jove" is the ablative of "Jupiter" (JusPater) hence already means by "Jupiter": "By Jove" is a tautology.

Equivalent expressions are found in other languages, too.
For example , Jove also appears in the Cornish language as "Yow". However, the 'polite society' explanation is not applicable here. Cornish society has always been more egalitarian than that of the neighbouring English, and at the same time the Cornish less inhibited in calling on deities in oaths. This they share with the other Celtic peoples, and very similar practice prevails within the Romance languages.
"By Jove!" in Cornish is "Re Yow!" or "Abarth Yow!" (abarth being "a" = of, and "parth" = part - meaning approximately 'in the name of, for the sake of'. The "p" in "parth" undergoes softening (lenition) to "b" after "a" = "of").
Also English "Thursday" (i.e. Thor's day, the day of the god Thor) is in Cornish "Dy' Yow" ( "dydh" = day "Yow"= Jove , so "day (of) Jove", "Jove's day".) The Cornish days of the week and months of the year are from a mixture of Celtic and Romance sources, compared with Teutonic and Romance sources in English.
