I have updated Eclipse to version 2019-03, and pulled the latest version of Poi
trunk from the Git mirror. Eclipse now builds POI without errors, but
apparently I cannot make use of it (see details below). I am trying to get
around this by going back to using Ant to build build.xml with the "jar"
target, but it fails during the test phase. I am an Ant newbie, so I can only
guess as to what is happening here.
When Ant fails, the following written is to the console:
[junit] Running org.apache.poi.TestXMLPropertiesTextExtractor
[junit] Tests run: 5, Failures: 0, Errors: 0, Skipped: 0, Time elapsed:
1.028 sec
[junit] Running org.apache.poi.extractor.ooxml.TestExtractorFactory
[junit] Tests run: 15, Failures: 0, Errors: 4, Skipped: 0, Time elapsed:
2.54 sec
BUILD FAILED
C:\Users\David M. Gauntt\git\poi\build.xml:1629: The following error occurred
while executing this line:
C:\Users\David M. Gauntt\git\poi\build.xml:1595: The following error occurred
while executing this line:
C:\Users\David M. Gauntt\git\poi\build.xml:1237: Tests failed
The lines of build.xml that cause the errors are:
<target name="test-ooxml"
depends="compile-main,compile-ooxml,-test-ooxml-check,jacocotask,-ooxml-lite-agent"
unless="ooxml.test.notRequired"
description="test OOXML classes">
// Fails on the following line
<ooxml-test-runner classpath="test.ooxml.classpath" type="ooxml"/>
<delete file="${ooxml.testokfile}"/>
<antcall target="-test-ooxml-write-testfile"/>
</target>
and
<macrodef name="ooxml-test-runner" xmlns:jacoco="antlib:org.jacoco.ant">
<attribute name="classpath"/>
<attribute name="type"/>
<sequential>
// Fails on the following line
<poiunit failureproperty="ooxml.test.failed" heap="768"
jacocodest="build/jacoco-@{type}.exec">
<classpath>
<path refid="@{classpath}"/>
<path refid="test.jar.classpath"/>
</classpath>
I will see if I can disable a test target as a jury-rig, but that doesn't seem
like the best possible solution.
Details on Eclipse failure
I had written a UnitTest project to run unit tests on Poi (and other software).
In Eclipse, I have added ApachePOI as a "Required Project" in the build path,
but I get the following in the Problem window:
"The type org.openxmlformats.schemas.spreadsheetml.x2006.main.CTWorksheet
cannot be resolved. It is indirectly referenced from required .class files"
I can get rid of this by adding two libarires that I downloaded from the
internet: "ooxml-schemas-1.4.jar" ad "ooxml-security-1.1.jar". When I do this
I can build and run the UnitTest project, but it appears to be executing the
XSSFSheet code in "ooxml-schemas-1.4.jar" rather than in the ApachePOI project,
which defeats the whole purpose of the UnitTest project.

Thanks for looking into this; I will try updating Eclipse and rebuilding
tonight.
I have also been working on building it using Ant within Eclipse; I will
post a question in the next day or two about my current problem with that.
