PDFBox half available

Question

I downloaded PDFBox 1.8.6 from Apache

Then I copied it to the "res" folder created in the root Java / Eclipse project. Then I right-clicked on the project, went to properties, then to the Java build path, then to Libraries, then clicked the Add JARS ... button and added it and my documentation.

From now on, in my code, I could import the (ish) PDFBox.

For example, I see:

import org.apache.pdfbox.pdmodel.*;

But, if you want to do something useful, you need to import more, often in the form:

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.edit.PDPageContentStream;
import org.apache.pdfbox.pdmodel.font.PDType1Font;
import org.apache.pdfbox.pdmodel.font.PDFont;

For some strange reason, I see, I don’t see these ...

Can someone please explain this to me?

• pdfbox-app-1.8.7.jar https://pdfbox.apache.org/download.cgi
• . PS: javadoc . .
• "org.apache.pdfbox.pdmodel.PDDocument;" ( org.apache.pdfbox.pdmodel, Ctrl + Space, ). .
• . . "org.apache.pdfbox.pdmodel.font.PDFont" "org.apache.pdfbox.pdmodel.font". Ctrl + Space, .
• I think you did "import org.apache.pdfbox.pdmodel. *;" therefore it displays all packages. For reference 3,4,5, select the appropriate package from the list of offers, and then press Ctrl + Space to get class offers inside this package. Also remove javadoc from the build path and check.

Hope this helps
