It's height nearly 20 feet it's in damp condition.
You can keep it pruned to about 15 feet to make harvesting easier. Also, since it isn't producing, I'm wondering if you are fertilizing. Besides nitrogen, phosphorous and potassium, your tree needs magnesium.
The damp condition may be preventing the fruit. Jackfruit trees do not like wet feet.

I trying to see if I can start growing jackfruit in Michigan and all that I need to get it done if possible
One thing these trees won't tolerate is wet feet, so if you live in a swampy, wetland-type area, you probably would not have much luck with them. Their origins are in much warmer climates than yours, however, if you protect it in the winter it should grow there.

A fully grown jackfruit tree(25 feet high) was giving a very good harvest till last year,but this year has completely dried,there is not a single green leaf,though this is the time it should bear fruits.The trunk of tree pink patches are seen here and there. Please advise what should be fone to revive it.
Here are two articles from the Australian government which may be your tree's problem. Another factor that contributes to tree decline is covering the root area with hardscape materials. It prevents oxygen from reaching the tree.

We bought a new house and there is an old jackfruit tree that's around 20 years. According to the neighbors, it used to bear good fruit many years back, but it was left abandoned for many years and it is not bearing any fruit now. After we bought the house, we see many new leaves growing on the tree, so I don't think it's dead. But its barks outer layer is dark and flaky and can be peeled off quite easily in some places. I'm not sure what's wrong with the tree. Can someone help?
Likely, the decline is due to fertilization issues. Feeding these will keep them productive, while staving off infections.

I live in western Australia
I suspect it isn't getting enough water or humidity. Also check for sucking insects like aphids and scale.

Hello, My 7-month old jackfruit seedlings were growing fine until about two months ago. They are all developing browning of the leaves, starting with the bottom ones and progressing to the upwards leaves until the plant dies completely. I am watering them daily and regularly, applied neem oil (though I cannot see any signs of pests), repotted them in fresh soil and bigger pots, and now have switched to filtered water instead of tap water to water them, but they do not seem to be recovering well. What do you think is the problem?! Thanks for your help!
I notice that the soil doesn't, quite, look like your typical potting soil. Likely, this is the problem, along with overwatering.
Check your soil for nutrient deficiencies, and add nutrients according to the test, or repot into a potting soil designed for fruit trees for a more simple solution.
