properties.setStartDate and task.setStart are not working

[djjty]

I'm not sure if there are any other factors that haven't been considered, but I used official examples to test and it seems that mpxj doesn't work on setting project time, task start time, and finish time. There is no time data in the generated xer file. Is there any other way?

example:

import jpype
import mpxj

jpype.startJVM()
from java.lang import Double
from java.time import LocalDate, LocalDateTime
from net.sf.mpxj import ProjectFile, TaskField, Duration, TimeUnit, RelationType, Availability, Relation
from net.sf.mpxj.common import LocalDateTimeHelper
from net.sf.mpxj.writer import UniversalProjectWriter, FileFormat

file_name = "test.xer"
file_format = FileFormat.XER

file = ProjectFile()

calendar = file.addDefaultBaseCalendar()

calendar.addCalendarException(LocalDate.of(2006, 3, 13), LocalDate.of(2006, 3, 13))

properties = file.getProjectProperties()
properties.setStartDate(LocalDateTime.of(2003, 1, 1, 8, 0))

properties.setProjectTitle("Created by MPXJ")
properties.setAuthor("Jon Iles")

customFields = file.getCustomFields()
field = customFields.getOrCreate(TaskField.TEXT1)
field.setAlias("My Custom Field")

resource1 = file.addResource()
resource1.setName("Resource1")

resource2 = file.addResource()
resource2.setName("Resource2")
resource2.getAvailability().add(Availability(LocalDateTimeHelper.START_DATE_NA, LocalDateTimeHelper.END_DATE_NA, Double.valueOf(50.0)));

task1 = file.addTask()
task1.setName("Summary Task")

task2 = task1.addTask()
task2.setName("First Sub Task")
task2.setDuration(Duration.getInstance(10.5, TimeUnit.DAYS))
task2.setActualDuration(Duration.getInstance(10.5, TimeUnit.DAYS))
task2.setStart(LocalDateTime.of(2015, 1, 1, 8, 0))
task2.setFinish(LocalDateTime.of(2015, 1, 1, 8, 0))
task2.setActualFinish(LocalDateTime.of(2015, 1, 1, 8, 0))
task2.setText(1, "My Custom Value 1")

task2.setPercentageComplete(Double.valueOf(50.0))
task2.setActualStart(LocalDateTime.of(2003, 1, 1, 8, 0))

task3 = task1.addTask()
task3.setName("Second Sub Task")
task3.setStart(LocalDateTime.of(2003, 1, 11, 8, 0))
task3.setDuration(Duration.getInstance(10, TimeUnit.DAYS))
task3.setText(1, "My Custom Value 2")

task3.addPredecessor(Relation.Builder().targetTask(task2))

milestone1 = task1.addTask()
milestone1.setName("Milestone")
milestone1.setStart(LocalDateTime.of(2003, 1, 21, 8, 0))
milestone1.setDuration(Duration.getInstance(0, TimeUnit.DAYS))
milestone1.addPredecessor(Relation.Builder().targetTask(task3))

task4 = file.addTask()
task4.setName("Next Task")
task4.setDuration(Duration.getInstance(8, TimeUnit.DAYS))
task4.setStart(LocalDateTime.of(2003, 1, 1, 8, 0))
task4.setPercentageComplete(Double.valueOf(70.0))
task4.setActualStart(LocalDateTime.of(2003, 1, 1, 8, 0))

assignment1 = task2.addResourceAssignment(resource1)
assignment2 = task3.addResourceAssignment(resource2)

assignment1.setWork(Duration.getInstance(80, TimeUnit.HOURS))
assignment1.setActualWork(Duration.getInstance(40, TimeUnit.HOURS))

assignment1.setRemainingWork(Duration.getInstance(40, TimeUnit.HOURS))
assignment2.setRemainingWork(Duration.getInstance(80, TimeUnit.HOURS))
assignment1.setStart(LocalDateTime.of(2003, 1, 1, 8, 0))
assignment2.setStart(LocalDateTime.of(2003, 1, 11, 8, 0))

task5 = file.addTask()
task5.setName("Last Task")
task5.setDuration(Duration.getInstance(3, TimeUnit.DAYS))
task5.setStart(LocalDateTime.of(2003, 1, 1, 8, 0))
task5.setPercentageComplete(Double.valueOf(100.0))
task5.setActualStart(LocalDateTime.of(2003, 1, 1, 8, 0))

task6 = file.addTask()
task6.setName("Last Milestone")
task6.setDuration(Duration.getInstance(0, TimeUnit.DAYS))
task6.setStart(LocalDateTime.of(2003, 1, 1, 8, 0))
task6.setPercentageComplete(Double.valueOf(100.0))
task6.setActualStart(LocalDateTime.of(2003, 1, 1, 8, 0))

writer = UniversalProjectWriter(file_format).write(file, file_name)

jpype.shutdownJVM()
